Hydrogen fuel is supplied to the anode, where a catalyst (typically platinum) splits the hydrogen molecules into protons ( H+cap H raised to the positive power ) and electrons ( e−e raised to the negative power
This layer allows positively charged protons to migrate through it to the cathode while acting as an insulator for electrons. Fuel Cell Fundamentals
Fuel cells are primarily classified by the type of electrolyte they use, which determines their operating temperature and suitable applications. Electrolyte Typical Temp. Common Applications Polymer Membrane 60–180 °C Vehicles (e.g., Toyota Mirai), portable electronics SOFC Solid Oxide (Ceramic) 500–1000 °C Large-scale stationary power, utility plants PAFC Phosphoric Acid 150–200 °C Large-scale stationary power generation MCFC Molten Carbonate Large stationary power, industrial use AFC Space missions (e.g., NASA shuttles) Key Components & Systems Fuel Cell Basics - FCHEA Hydrogen fuel is supplied to the anode, where
Fuel cells are electrochemical devices that generate electricity through a chemical reaction without combustion, typically by combining hydrogen and oxygen. Unlike batteries, which store a finite amount of energy, fuel cells produce power continuously as long as fuel and an oxidant are supplied. Core Working Principles industrial use AFC Space missions (e.g.
