An apparatus for co-production of electricity and hydrogen by gas-liquid self-separation

Abstract

The application discloses a kind of gas-liquid self-separation electric hydrogen co-production device, including anode flow field plate, cathode gas-liquid self-separation flow field plate, anode electrode and cathode electrode of load noble metal catalyst, and the cation membrane of the division anode electrode and cathode electrode;The cathode gas-liquid self-separation flow field plate is divided into reaction zone and separation zone by the partition rib of vertical arrangement, and reaction zone and separation zone are communicated by the flow channel above partition rib, and reaction zone flow channel is arranged in reaction zone;Cathode gas-liquid self-separation flow field plate is divided into reaction zone and separation zone, and is arranged in the mode of subarea, and it is convenient to design and optimize separately for cell performance and separation effect, guarantee the high performance of cell in reaction zone and the efficient separation of separation zone, the flow field design of self-separation avoids additional gas-liquid separation device, improves the integration and easy use of electric hydrogen co-production device, improves the reliability of gas-liquid separation, reduces the difficulty of gas-liquid separation flow field optimization design.
