Hydrogen fuel cells have been in use since the 19th century, with the first practical fuel cell developed by Sir William Grove in 1839. However, they gained significant attention and development during the 20th century, particularly in the 1960s for space applications. Since then, hydrogen fuel cells have been increasingly adopted for various uses, including transportation and stationary power generation, as interest in clean energy technologies has grown.

What are some pros and cons of fuel cells?
Some pros of fuel cells are that it is: -efficient -produces no odor, no noise -reliable -environmentally friendly -is indefinetely renewable, as long as hydrogen is harvested Some cons of fuel cells are: - fuel cells are expensive -you have to harvest hydrogen, which is hard -The volume of the fuel cells are larger than the average internal combustion engine.
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.
Why is a fuel cell useful in spacecraft?
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
What is A voltaic cell in which a fuel substance undergoes oxidation and from which electrical energy is obtained continuously?
A voltaic cell that uses a fuel substance undergoing oxidation to produce electrical energy continuously is known as a fuel cell. Fuel cells are electrochemical devices that convert chemical energy from a fuel into electricity through redox reactions, with hydrogen or hydrogen-containing compounds being common fuel sources. Unlike batteries, fuel cells can operate continuously as long as the fuel and oxidizer are supplied.
How do hydrogen fuel cells work?
The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions.The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out. In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
Why should hydrogen be the fuel of the future?
To save the environment and make sure that the world do not go under. ---- Hydrogen is found in water that we have a lot of, using electrolysis we could draw out hydrogen and oxygen in separate gases. In modern cars, we could stake rows of fuel cells that use the hydrogen we just made; this cell produces electrical currency that powers the car. In addition, out of the exhaust it will drip water.
What is a fuel cell and why is it important for spacecraft?
A fuel cell is an electrochemical device that converts chemical energy into electrical energy. It is important for spacecraft because it provides a reliable and efficient power source for long-duration missions in space. Fuel cells can generate electricity using hydrogen and oxygen as fuel, producing water as a byproduct, which is crucial for life support systems on spacecraft.

What is the cost of fuel cell energy?
I am not able to give you a cost, as there are a number of fuel cell technologies, and it will be difficult to know which ones might ultimately become commercial. So far, fuel cells applications have required large government subsidies. The "hydrogen car" is still apparently a long ways from becoming a reality- see related links.
Why is hydrogen a bad fuel?
It would be simplistic to claim that hydrogen is a bad fuel, but hydrogen does present certain complications as a fuel. Because it is a gas, it is not as easy to store as a liquid fuel such as gasoline. And depending upon how it is stored, it is more likely to explode, in the event of an accident, than gasoline would be. But in some ways hydrogen is an excellent fuel. The only combustion product of burning hydrogen is water. It is completely nonpolluting. And since hydrogen can be made from water (by electrolysis) there is in principle an unlimited supply, as long as you can generate the electricity needed to perform the electrolysis.
How are fuel cells different from conventional batteries in terms of their energy storage and conversion mechanisms?
Fuel cells differ from conventional batteries in their energy storage and conversion mechanisms. While batteries store energy in chemical form within the cell, fuel cells generate electricity through a chemical reaction between a fuel source and an oxidizing agent. This allows fuel cells to continuously produce electricity as long as fuel is supplied, unlike batteries which have a limited capacity and need to be recharged.
