A hydrogen fuel cell produces energy through an electrochemical reaction between hydrogen and oxygen. Hydrogen gas is fed into the anode side of the fuel cell, where it is split into protons and electrons. The protons travel through an electrolyte membrane to the cathode side, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons, electrons, and oxygen from the air combine to produce water and release energy in the form of electricity. **

Green Arrow practices archery as his primary martial art. He is highly skilled in using a bow and arrow, which he uses as his main weapon in combat. His accuracy and precision with the bow make him a formidable fighter, allowing him to take down enemies from a distance with ease. **

A hydrogen fuel cell is a device that converts the chemical energy of hydrogen and oxygen into electricity through an electrochemical reaction. It consists of an anode, a cathode, and an electrolyte membrane. Hydrogen gas is fed into the anode, where it is split into protons and electrons. The protons pass through the electrolyte membrane to the cathode, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons, electrons, and oxygen from the air combine to produce water and heat as byproducts. This process is clean and efficient, making hydrogen fuel cells a promising alternative to traditional combustion engines. **
