Hydrogen Fuel Cells

Hydrogen fuel cells are devices that convert chemical energy from hydrogen into electrical energy through a electrochemical reaction with oxygen, typically derived from air. In a hydrogen fuel cell, hydrogen gas (H2) enters the anode side of the cell, where it is split into protons and electrons. The protons move through a membrane to the cathode, while the electrons are routed through an external circuit, creating an electric current. At the cathode, oxygen (O2) combines with the protons and electrons to produce water (H2O) as a byproduct. This process generates electricity efficiently and emits only water vapor and heat, making hydrogen fuel cells a clean energy source. They are used in various applications, including transportation (such as fuel cell vehicles), stationary power generation, and backup power systems. Hydrogen fuel cells are recognized for their potential to reduce greenhouse gas emissions and dependence on fossil fuels, contributing to more sustainable energy solutions.
