ACTIVATING METHOD OF CATALYST FOR SOLID POLYMER FUEL CELL, AND ACTIVATED CATALYST FOR SOLID POLYMER FUEL CELL

摘要

PROBLEM TO BE SOLVED: To improve cell performance by activating a catalyst for a fuel cell.

SOLUTION: This activating method of the catalyst for the solid polymer fuel cell is to apply a potential to the catalyst for the solid polymer fuel cell using a prescribed potential application pattern. The potential application pattern includes (1) a potential dropping process to drop a potential to a lower limit reduction potential from an initial potential, (2) a lower limit reduction potential holding process to hold the reduction potential, and (3) a potential elevating process to elevate the potential from the lower limit reduction potential to the initial potential.
