    • Fuel cell emergency power systems comprising a fuel cell having an anode and a cathode, a power distribution unit for selectively directing electrical current from the fuel cell to one or more consuming device, a hydrogen gas control system and an oxygen gas control system. The hydrogen gas control system includes a pressurized hydrogen tank providing hydrogen gas in selective fluid communication to the anode, a hydrogen gas-liquid water phase separator in downstream fluid communication with the anode, and a hydrogen recirculation pump for recirculating substantially liquid water-free hydrogen from the hydrogen gas-liquid water phase separator to the anode. Similarly, the oxygen gas control system includes a pressurized oxygen tank providing oxygen gas in selective fluid communication to the anode, an oxygen gas-liquid water phase separator in downstream fluid communication with the anode, and an oxygen recirculation pump for recirculating substantially liquid water-free oxygen from the oxygen gas-liquid water phase separator to the anode.

    • A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.
    • 一种用于电化学合成氨气的方法,包括在阳极和阴极之间提供电解质,向阳极提供氢气,在阳极处氧化存在于电解质中的带负电荷的含氮物质以形成吸附的氮物质,并使 氢与吸附的氮物质形成氨。 优选地,通过使氢气通过多孔阳极基板而将氢气提供给阳极。 还优选通过还原阴极处的氮气来在电解质中产生带负电的含氮物质。 然而,带负电的含氮物质也可以通过向熔融盐电解质混合物中提供足够量的含氮盐(例如氮化钠)来提供在氨生产中消耗的一部分或全部氮 。
