What is and how does a hydrogen fuel cell works?
A hydrogen fuel cell is a device for the electrochemical energy conversion of hydrogen. When hydrogen gets into the fuel cell, a membrane coated with catalyst separates hydrogen into protons and electrons. The free electrons are conducted through an external circuit producing electrical current that can be used to produce motion through electrical motors. Once finished, the process combine back the protons and electrons with oxygen obtained from air to produce water and heat as by-products.
