How does hydrogen fuel cell work?

Just curious

A hydrogen fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen. H2 is supplied to the negative electrode of the fuel cell where each hydrogen molecule splits into two protons and two electrons. Electrons cannot pass through the electrolyte so they are forced to travel through an external circuit, creating an electric current. The byproduct of hydrogen fuel cells is H2O so they are highly sustainable.

In addition to being highly sustainable due to their production of water as the only byproduct, hydrogen fuel cells offer several other advantages. Firstly, they have high efficiency compared to traditional combustion engines, as they can convert a larger portion of the chemical energy in hydrogen fuel into electricity. This efficiency can help reduce energy consumption and greenhouse gas emissions, contributing to efforts to combat climate change. Furthermore, hydrogen fuel cells can be refueled relatively quickly, similar to conventional vehicles, making them suitable for applications where fast refueling or recharging is necessary, such as in transportation. They also have a longer range compared to battery-powered electric vehicles, which may require longer charging times and have limited driving ranges.
