PROBLEM TO BE SOLVED: To provide a solid electrolyte type fuel cell, having increased power- generating effect by forming a coating, composed of a noble metal, on a surface abutting a fuel pole in an interconnecting surface. SOLUTION: A plate-type solid electrolyte type fuel cell is constituted by nipping a single cell 5 composed of an air pole 2 on an upper surface part, and a fuel pole 3 on a lower surface with an electrolyte 1 nipped by an air side interconnector 4a, wherein an air passage groove 8 is formed from an upper side to a lower surface, and a fuel side interconnector 4b wherein a fuel gas passage groove 7 is formed from the lower side to the upper side to adopt the cell 5 as a single cell stack 10, and repeating this procedure to laminate the single cells 5. Noble metal coating (Ni) is formed on the portion, where these interconnectors 4a and 4b abut a fuel pole 3, so that a coating thickness is about 1 - a few tens of microns by a vapor-repositioning method, a PV method such a spattering method, a CVD method such as plasma and a laser, a slurry method, and an electrodeposition method, etc. This can considerably reduce electrical resistance for the interconnectors under a high-temperature and a reducing atmosphere. |
