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 depending on the application, a fuel cell stack may contain a few to hundreds of individual fuel cells layered together. Finally, the flexibility regarding possible fuels — with secondary energy carriers produced from natural gas, coal, crude oil as well as biomass, solar energy and other renewable energy sources being suitable primary energy carriers — places fuel cells in a “hybrid” position between fossil and renewable fuels. Vehicles the fuel cell system power response is limited only by the air and hydrogen feed, ﬂow and pressure regulation, and heat and water management as current is instantaneously drawn from the load source connected to the fuel cell stack, heat and water are generated, whereas oxygen is depleted.
