Fuel Cell

Table of Contents


Hydrogen fuel cells are units which produce electricity through a reaction of positively charged hydrogen ions with oxygen or another oxidixing agent, i.e. separating electrons from the oxidizing agent by having it react with the positively charged hydrogen ion. This is performed through the usage of a anode, a cathode, and a catalyst.
