Molecular fuel production during electricity generation is an elusive challenge in the chemistry of energy devices offering tremendous possibilities in the sustainable energy landscape. We illustrate an inherent-heat-driven electrochemical cell (IHEC) where the heat of neutralization can be tapped as electromotive force for simultaneous power (∼70 mW/cm²) and molecular fuel (∼70 mL/hour) production. By coupling fuel and electricity generation in the same device, IHEC offers a paradigm shift in the chemistry of energy devices by its capability to directly fuel a proton exchange membrane fuel cell without any hydrogen storage unit.

一种固有的热驱动呼气肼燃料电池

发电过程中的分子燃料生产是能源设备化学中一个难以捉摸的挑战，在可持续能源领域提供了巨大的可能性。我们说明了一个固有的热驱动电化学电池（IHEC），其中中和的热量可以作为电动势利用，以同时生产功率（〜70 mW / cm ²）和分子燃料（〜70 mL /小时）。通过将燃料和发电耦合在同一设备中，IHEC通过直接为质子交换膜燃料电池提供燃料而无需任何储氢单元的能力，为能源设备的化学性质带来了范式转变。
