A fabrication process for production of SOFC-MEA with a pore array anode structure for improving output power density

摘要

A fabrication process for production of planar type solid oxide fuel cell with high electrical conductivity and low fuel gas impedance is disclosed. It is a tape casting to produce an anode substrate furnished with a pore array structure on one or plurality of layers of the anode green tape on the utmost outside of the anode. It is to implement the process of solid oxide fuel cell membrane electrode assembly (SOFC-MEA) with precision abrasion to remove nickel depleted layer on the anode surface to complete the production of a unit cell. The fabrication of anode with pore array structure provides a good conduction effect for fuel gas and the solid oxide fuel cell with this treatment has features of high electrical conductivity and low fuel gas impedance to improve the performance of SOFC unit cell.
