Hydrogen fuel cells typically have a lifespan ranging from 5,000 to 25,000 hours of operation, depending on factors like the design, operating conditions, and maintenance. In automotive applications, they can last over 200,000 miles before performance significantly degrades. Advances in technology continue to improve durability and efficiency, potentially extending their service life further. Regular maintenance and optimal operating conditions can also help maximize their longevity.

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.
How long has hydrogen fuel cells been used?
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.
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.
What type of fuel will never run out?
none, hydrogen will last a very long time, easily to the end of human life, but it will eventually run out
How long does a hydrogen car last?
Who knows as there are no hydrogen cars in production.
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
Is a fuel cell a primary cell or secondary cell?
A fuel cell is neither a primary cell nor a secondary cell; it operates on a different principle. While primary cells provide electrical energy from a chemical reaction and cannot be recharged, and secondary cells can be recharged after discharging, fuel cells generate electricity through an ongoing reaction between fuel (like hydrogen) and an oxidizer (like oxygen). This process continues as long as fuel is supplied, making fuel cells a unique energy source.
How long is hydrogen going to last on earth?
Forever. Hydrogen can be created from water.
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 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.
What is the Difference between electrochemical cell and fuel cell?
An electrochemical cell is a device that converts chemical energy into electrical energy through redox reactions, and it can function in both galvanic (battery) and electrolytic modes. A fuel cell, on the other hand, is a specific type of electrochemical cell that continuously converts the chemical energy of a fuel (usually hydrogen) and an oxidant (like oxygen) into electricity, water, and heat, as long as fuel is supplied. In essence, while all fuel cells are electrochemical cells, not all electrochemical cells are fuel cells; the latter has a continuous reactant supply and often operates at higher efficiencies.
