    • The invention provides a high-pressure hydrogen production apparatus for preventing hydrogen gas from leaking toward an anode side and for obtaining excellent electrolytic efficiency. The apparatus includes a single cell having a solid polymer electrolyte membrane, power feeders, separators, and fluid channels provided in respective separators. High-pressure hydrogen gas accompanied by water is obtained in the fluid channel by supplying water to the fluid channel and applying current to each power feeder to electrolyze water. The obtained hydrogen gas and water are subjected to gas-liquid separation in a second compartment of a high-pressure vessel, and hydrogen gas thus separated is used to press a barrier member towards the single cell. The separated water is supplied to the fluid channel through the hydrogen gas guide channel.
    • 本发明提供一种用于防止氢气向阳极侧泄漏并获得优异的电解效率的高压氢气制备装置。 该装置包括具有固体聚合物电解质膜的单电池,供电装置,分离器和设置在各个隔板中的流体通道。 通过向流体通道供水并向每个供电器施加电流以电解水,在流体通道中获得伴随水的高压氢气。 将获得的氢气和水在高压容器的第二室中进行气液分离,并且使用如此分离的氢气将阻挡构件朝向单电池按压。 分离的水通过氢气引导通道供应到流体通道。
