Fuel cells come in many varieties; however, they all work in the same general manner. They are made up of three adjacent segments: the anode, the electrolyte, and the cathode. Two chemical reactions occur at the interfaces of the three different segments. The net result of the two reactions is that fuel is consumed, water or carbon dioxide is created, and an electric current is created, which ca… WebThe overall reaction of a hydrogen-oxygen fuel cell is: A 2H2(g)+O2(g)→2H2O(l) B 2H2(g)+4OH−(aq)→4H2O(l)+4e− C O2(g)+2H2O(l)+4e−→4OH(aq) D 2H2O(l)→2H2(g)+O2(g) Solution The correct option is A 2H2(g)+O2(g)→ 2H2O(l) high ping when downloading https://brucecasteel.com
