How do fuel cells compare to electrochemical cells?
Fuel cells and electrochemical cells both convert chemical energy into electrical energy through electrochemical reactions, but they differ in operation and design. Fuel cells continuously convert reactants (usually hydrogen and oxygen) from an external source, producing electricity as long as fuel is supplied. In contrast, electrochemical cells, such as batteries, store energy and release it through a one-time chemical reaction until the reactants are depleted. Additionally, fuel cells typically have higher efficiency and lower emissions compared to traditional batteries.
How does a fuel cell differ from other types of cells?
A fuel cell differs from other types of cells, such as batteries, in that it generates electricity through a continuous chemical reaction rather than storing energy. Fuel cells convert the chemical energy of a fuel (typically hydrogen) and an oxidant (usually oxygen) directly into electrical energy, producing water and heat as byproducts. Unlike batteries, which require recharging after their stored energy is depleted, fuel cells can operate as long as they are supplied with fuel and oxidant. Additionally, fuel cells are often more efficient and environmentally friendly compared to traditional combustion-based power sources.
What is the Storage of energy is a major function of?
Storage of energy is a major function of fat cells in the body. Excess energy from food is converted into triglycerides and stored in fat cells to be used as fuel when needed.
Why do spacecrafts use fuel cells?
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.
Fuel cells produce energy from hydrogen by?
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
Can fuel cells for cars be mass produced cheaply?
Yes. Mass producing cars is not the problem. The fuel for fuel cells is too expensive, so far.
The major energy fuel for the central nervous system?
Glucose is the major energy fuel for the central nervous system. It is required for brain function and plays a critical role in cognitive processes. Brain cells rely heavily on a constant supply of glucose for energy production.
What major fuel is used for the cell's activities in the human body?
Cells primarily use carbohydrates, especially glucose, which is broken down during cellular respiration, forming molecules of ATP, which are used by the cells in order to get energy to do work (cellular activities). Cells get energy from ATP molecules when they are broken down into ADP and P, which releases energy.
What molecule is the major fuel used by cells?
The major fuel used by cells is glucose. Glucose is a simple sugar that provides the energy needed for cellular processes through the process of cellular respiration.
What major fuel is used in cell activities?
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.
59 What is the major energy carrier molecule in most cells?
The major energy carrier molecule in most cells is adenosine triphosphate (ATP). ATP is generated through cellular respiration and stores energy that can be used by the cell to fuel various metabolic processes.
Why are fuel cells considered a clean energybsource?
Fuel cells are considered a clean energy source because they generate electricity through an electrochemical reaction between hydrogen and oxygen, producing only water and heat as byproducts. This process emits no harmful pollutants or greenhouse gases, making it environmentally friendly. Additionally, when hydrogen is sourced from renewable energy, the overall carbon footprint of fuel cells is significantly reduced, further enhancing their sustainability. As a result, fuel cells offer a promising alternative to traditional fossil fuels in achieving cleaner energy solutions.
