Benefits include: Fuel cells have a higher efficiency than diesel or gas engines. Most fuel cells operate silently, compared to internal combustion engines. Fuel cells can eliminate pollution caused by burning fossil fuels; for hydrogen fuelled fuel cells, the only by-product at point of use is water.
Furthermore, how is a fuel cell made?
If free electrons or other substances could travel through the electrolyte, they would disrupt the chemical reaction. Whether they combine at anode or cathode, together hydrogen and oxygen form water, which drains from the cell. As long as a fuel cell is supplied with hydrogen and oxygen, it will generate electricity.
What are the different types of fuel cells?

- Reversible fuel cells.
Who uses hydrogen fuel cells?
NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct - pure water, which the crew drinks. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water.
