TEST METHOD OF POLYELECTROLYTE TYPE FUEL CELL, AND POLYELECTROLYTE TYPE FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide a test method of a fuel cell for guaranteeing the performance of the fuel cell by grasping beforehand a deterioration phenomenon of the polyelectrolyte at the time of operation of the fuel cell, and a fuel cell having high reliability. PSOLUTION: This is a test method of a polyelectrolyte fuel cell which generates electric power by an electrochemical reaction by supplying a fuel gas and an oxidizer gas, and comprises an acceleration operation process of carrying out operation in a state where the operation temperature of the polyelectrolyte fuel cell is higher than the rated operation time and a judgement process of judging whether the polyelectrolyte fuel cell is acceptable or not acceptable based on the result of the acceleration operation.
