How Fuel Cells Work
A fuel cell harnesses the electricity created in the chemical reaction that occurs when hydrogen and oxygen are combined. Hundreds of fuel cells are "stacked" together, combining their electrical outputs into enough electricity to power a car. In the not-too-distant future, fuel cells will change how we live our everyday lives. They will power our vehicles, homes and office buildings more efficiently and with significantly less impact on the environment than fossil fuels. Fuel cell technology could end energy shortages and reduce reliance on imported oil. Before that day comes, however, four important challenges - hydrogen storage, cost reduction, durability and infrastructure development - must be solved. GM is working to solve these problems.
