Fuel Cell and Combustion

A fuel cell is a device that transforms chemical potential energy (energy stored in molecular bonds) into electrical energy. A PEM (Proton Exchange Membrane) cell needs hydrogen gas (H2) and oxygen gas (O2) as fuel. The amount of the reaction in the cell are water, electricity, and heat. This is a big advancement over internal combustion engines, coal burning power plants, and nuclear power plants, all of which produce unhealthy by-products.

By transforming chemical potential energy exactly into electrical energy, fuel cells bypass the “thermal bottleneck” (a consequence of the 2nd law of thermodynamics) and are thus naturally more adequate than combustion engines, which must first transforms chemical potential energy into heat, and then mechanical work.
