An alkaline-acid Zn-H O fuel cell is proposed for the simultaneous generation of electricity with an open circuit voltage of about 1.25 V and production of H with almost 100 % Faradic efficiency. We demonstrate that, as a result of harvesting energy from both electrochemical neutralization and electrochemical Zn oxidation, the as-developed hybrid cell can deliver a power density of up to 80 mW cm and an energy density of 934 Wh kg and maintain long-term stability for H production with an output voltage of 1.16 V at a current density of 10 mA cm .
