OPERATION METHOD FOR HIGH-TEMPERATURE TYPE FUEL CELL, AND HIGH-TEMPERATURE TYPE FUEL CELL

摘要

PURPOSE: To restrict the deterioration at the time of operation under heat cycle load, or the deterioration such as distortion by contact resistance or thermal stress by repeated application of the heat cycle load especially. CONSTITUTION: In operation of a high-temperature type fuel cell having an electrode terminal separator 12, and an output terminal which faces it to electrically get in contact with it under heat cycle load, a buffer layer 13a which restricts deterioration by the heat cycle load is provided between the separator 2 and the output terminal. Otherwise, a high-temperature type fuel cell is provided having a terminal collector member comprising an electrode terminal separator, buffer material which restricts deterioration by heat cycle load, and an output terminal integrated with each other in order.
