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

研制了一种新型制氢装置，利用铂电极与透氢钯膜之间的导电作用对水进行电解，生产出高纯度的氢气。最大工作压力为2 MPa。在常温下，随着温度的升高，电解作用加快，氢渗透率增加，说明高温区更有利于产氢和氢渗透。此外，还开发了利用电解侧钯膜渗透氢气的加氢装置。在钯膜的渗透侧加入加氢催化剂层，实现了芳香族化合物的加氢反应。

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.
