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

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 Fuel Cell Fundamentals

This layer allows positively charged protons to migrate through it to the cathode while acting as an insulator for electrons. Hydrogen fuel is supplied to the anode, where

The basic operation of a fuel cell relies on a that occurs across three primary components: an anode, a cathode, and an electrolyte membrane. The basic operation of a fuel cell relies

Because the electrons cannot pass through the membrane, they are forced through an external circuit, which creates the electric current used to power a load.

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

At the cathode, the electrons rejoin the protons and combine with oxygen (usually from the air) to produce the cell's only byproducts: water and heat . Major Fuel Cell Types
