DEVICE AND METHOD FOR EVALUATING PERFORMANCE OF FUEL CELL, DEVICE AND METHOD FOR EVALUATING SPECIFIC SURFACE AREA OF ELECTRODE CATALYST FOR FUEL CELL, AND ELECTRODE CATALYST FOR FUEL CELL AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To simply accurately evaluate the performance of a fuel cell. SOLUTION: After an electrode catalyst sample S is placed on a sample placement board 110, a hydrogen gas of 80 degrees C is distributed in a sample storage device 100 via a hydrogen gas supply device 200 for 15 minutes. Then, a 100% carbon monoxide gas is pulse-injected into the sample storage device 100 via a carbon monoxide gas supply device 300 for detecting the amount of carbon monoxide gas exhausted by a carbon monoxide gas detector 400. A processor 600 calculates the amount of carbon monoxide gas adsorbed into the electrode catalyst sample S by subtracting the detected amount of carbon monoxide gas from the supplied amount of carbon monoxide gas and calculates the output voltage of the fuel cell from a correlation between the calculated amount of carbon monoxide gas adsorbed into the electrode catalyst and the output voltage of the fuel cell.
