Development of hydrogen permeable electrolysis cell for continuous hydrogen production from high temperature water

开发了通过铂电极和氢渗透性钯膜之间的导电来电解水的创新制氢装置，以生产高纯氢。 最大操作压力为2MPa。 在常压下，随着温度的升高，电解得到促进，氢渗透率增加，说明在高温区优先进行氢气的产生和渗透。此外，还开发了利用水电解侧钯膜渗透氢的加氢装置。 通过在钯膜的透过侧添加加氢催化剂层，实现了芳烃的加氢。

Innovative hydrogen production apparatus that electrolyzes water by means of conduction between platinum electrode and hydrogen permeable palladium membrane was developed to produce highly pure hydrogen. The maximal operating pressure was 2 MPa. The electrolysis was promoted and hydrogen permeability increased with increasing temperature at ambient pressure, which means that hydrogen production and hydrogen permeation was preferred in high temperature region.Further, hydrogenation apparatus utilizing hydrogen permeated through palladium membrane from water electrolysis side was also developed. The hydrogenation of aromatic compounds occurred by the addition of hydrogenation catalyst layer on the permeation side of palladium membrane.
