Hydrogen Fuel Cell Simulator

Interactive hydrogen fuel cell simulator: watch H2 molecules split into protons and electrons at the anode, drive a current through an external circuit, and recombine with O2 at the cathode to form water. Tune fuel feed rate, circuit load and temperature in real time.

A hydrogen fuel cell converts chemical energy directly into electricity through the reaction 2H2 + O2 → 2H2O, without combustion. This simulator visualizes that process end to end: hydrogen molecules arriving at the anode are split into protons that cross a membrane and electrons that are routed through an external circuit as a working current, lighting a bulb before rejoining the protons and oxygen at the cathode to form water droplets. Adjust the hydrogen feed rate, circuit load and stack temperature to see how each changes the current, cell voltage and overall efficiency in real time.
