Omg, lol. only answer if you know a hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as 1. heat 2. chemical energy 3. electrical energy. when used at home, a fuel cell eliminates the need for 1. oxygen 2. hydrogen 3. an electrical grid because the cell is portable.
