Fuel cells, also known as hydrogen fuel cells, are advanced energy conversion devices that generate electricity by combining hydrogen & oxygen to produce water vapor & electricity. They are an alternative power source to internal combustion engines & utilize a chemical reaction rather than burning fuel. In a car fuel cell system, hydrogen gas is supplied to the anode side of the fuel cell, while oxygen from the air is supplied to the cathode side. The hydrogen atoms are split into protons & electrons, with the protons passing through the electrolyte membrane & the electrons creating an electrical current that can be used to power the vehicle's electric motor. The protons & electrons recombine with oxygen on the cathode side, producing water vapor as the only byproduct. Car fuel cells offer several advantages, including zero emissions, high energy efficiency, & quiet operation. However, they also present challenges such as hydrogen infrastructure development & cost. Nonetheless, fuel cell technology holds promise for clean & sustainable transportation in the future.
