Fuel cells offer tremendous potential as a clean power source. The chemical energy of hydrogen and oxygen reacts with fuel cells and converts the energy to electricity. The decades-old technology is ideal for a wide variety of applications, including stationary power stations and many forms of transportation.
A single fuel cell consists of an electrolyte sandwiched between two electrodes. Bipolar plates on either side of the cell help distribute gases and serve as current collectors. Fuel cells are easily scalable. Depending on the application, a fuel cell stack may contain hundreds of individual fuel cells layered together.
