DEVICE AND METHOD FOR EVALUATING PERFORMANCE OF FUEL CELLS, DEVICE AND METHOD FOR EVALUATING SPECIFIC SURFACE AREA OF FUEL-CELL ELECTRODE CATALYSTS, FUEL-CELL ELECTRODE CATALYST, AND METHOD OF MANUFACTURING THE SAME

摘要

A device and a method for simply and accurately evaluating performance of fuel cells have been provided. Hydrogen gas and carbon monoxide gas are caused to flow into a sample holder where an electrode catalyst sample is laid, and the amount of carbon monoxide gas discharged therefrom is detected. The amount of carbon monoxide gas adsorbed by the electrode catalyst samp le is calculated based on the amount of supplied carbon monoxide gas and the amount of detected carbon monoxide gas. The output voltage of a fuel cell is calculated based on a correlation between calculated amounts of carbon monoxide gas adsorbed by the electrode catalyst and output voltages of the fuel cell.
