Fuel Cells

Hydrogen fuel cells can significantly impact society by promoting cleaner energy solutions, which can reduce urban air pollution and improve public health. Their implementation can also create jobs in the green technology sector and stimulate economic growth through new industries. Furthermore, hydrogen fuel cells can enhance energy security by diversifying energy sources and reducing dependence on fossil fuels. However, challenges such as infrastructure development and public acceptance must be addressed for widespread adoption.

It is not recommended to create a fuel cell for a sky lantern as it can be dangerous. Commercially available sky lanterns are designed with safe fuel cells that should be used as intended. It is important to follow the manufacturer's instructions to ensure the safe use of sky lanterns.

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction. It is useful in spacecraft because it provides a reliable and efficient way to generate power in space without the need for combustion. Fuel cells have high energy density, are lightweight, and produce clean electricity, making them ideal for use in space where reliability and efficiency are crucial.

The fuel cell oxygen tanks on the Apollo 13 spacecraft malfunctioned on April 13, 1970, during the mission to the Moon. This failure resulted in a critical situation that jeopardized the lives of the astronauts on board.

Because a fuel cell converts the chemical energy of a fuel and an oxidant into electricity. This means that the space craft uses this electricity to work. It is basically like a giant battery which powers the space craft.

Hope this answers your question.

A fuel cell is important to a spacecraft because it provides a reliable and efficient source of electrical power by converting chemical energy directly into electricity without combustion. This is crucial for powering critical systems, such as life support and communication, in space missions where traditional power sources like solar panels may not be as effective. Additionally, fuel cells generate water as a byproduct, which can be used for various applications in space.

When fuel cells are shut down, astronauts cannot generate electrical power for the spacecraft, leading to a loss of energy for life support systems, communication equipment, and other critical spacecraft functions. This can impact the ability to maintain a safe and habitable environment in space.

Spacecraft use fuel cells because they are lightweight, efficient, and reliable sources of power. Fuel cells can generate electricity by combining hydrogen and oxygen, producing water as a byproduct, making them a clean energy solution for space missions. Additionally, fuel cells can provide continuous power for long-duration missions in space.

they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells

Because fuel cells do actually fart it's well documented. And they do a poo when they get tired! < SOOO TRUE!!

because hydrogen is in the fuel cell. hydrogen is useful in many things including spacecrafts. please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true. I know for sure that hydrogen is used for rocket fuel because it is on the sheet. By Georgina thank you 4 going on wikianswers.com

Humans have a complex circulatory system to efficiently transport oxygen, nutrients, hormones, and waste products to and from cells throughout the body. Amoebas, being single-celled organisms, can rely on simple diffusion to exchange gases and nutrients with their environment due to their small size and surface area.

The testes are responsible for producing male gametes, which are sperm cells. Sperm production occurs within the seminiferous tubules of the testes through a process called spermatogenesis.

Fuel cells are important to Earth because they provide a clean and efficient way to generate electricity without producing harmful emissions like greenhouse gases or pollutants. They can help reduce our reliance on fossil fuels and contribute to a more sustainable energy future by using hydrogen, a clean energy carrier that can be produced from renewable sources.

Hydrogen peroxidase is an enzyme that breaks down hydrogen peroxide. It is typically found in organelles called peroxisomes within the cell, where it helps to regulate reactive oxygen species levels and protect the cell from oxidative damage.

Hydrogen fuel is not inherently bad, but there are challenges associated with its widespread adoption such as high production costs, lack of infrastructure for distribution, and the carbon footprint of current production methods. Additionally, storing and transporting hydrogen can be difficult due to its low energy density.

Spacecraft fuel tanks are typically made of lightweight materials like aluminum or carbon fiber composites. These materials are chosen for their strength, durability, and low weight to maximize fuel efficiency and payload capacity. The tanks are also designed to withstand the extreme conditions of space travel, including temperature changes and high pressures.

The major elements in a microbial cell include carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are essential for various cellular processes such as energy production, metabolism, and macromolecule synthesis. Additionally, microbial cells may also contain trace elements like iron, magnesium, and potassium for enzyme function and structural stability.

Hydrogen combustion produces water vapor as the main byproduct, which is cleaner than the pollutants emitted from burning fossil fuels like gasoline or diesel. This results in less pollution being released into the atmosphere when hydrogen is used as fuel.

The membrane electrode assembly (MEA) is the main part of a fuel cell that is made out of a polymer. It consists of a polymer electrolyte membrane sandwiched between two catalyst-coated electrodes. The polymer membrane allows for the movement of ions while blocking the passage of gases.

Glucose is the major fuel used in cell activities. Cells break down glucose through a process called cellular respiration to produce energy in the form of ATP.

Living cells primarily use glucose as a source of fuel to produce energy through a process called cellular respiration. Glucose is broken down in a series of reactions to generate adenosine triphosphate (ATP), which is used as the main energy currency in cells. Some cells can also use other molecules such as fatty acids and amino acids for energy production.

The cell that can produce hydrogen gas fuel by using electricity to decompose water is an electrolyzer. Electrolyzers use an electric current to split water (H2O) into hydrogen (H2) and oxygen (O2) gases through a process called electrolysis.

Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing water as the only byproduct. Hydrogen fusion, on the other hand, involves combining hydrogen isotopes under high temperature and pressure to release energy, mimicking the process that powers the sun. Fusion has the potential to generate much more energy than fuel cells but is still in the research and development stage for practical applications.

The main element used in fuel cells is typically hydrogen, which is combined with oxygen to produce electricity through an electrochemical reaction.

The main fuel source for the work of the cell is the mitochondria.
