摘要：

An alkaline-acid Zn-H2O fuel cell is proposed for the simultaneous generation of electricity with an open circuit voltage of about 1.25V and production of H-2 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(-2) and an energy density of 934 Wh kg(-1) and maintain long-term stability for H-2 production with an output voltage of 1.16V at a current density of 10 mA cm(-2).
