FUEL CELL ELECTRODE AS WELL AS METHOD FOR MANUFACTURING FUEL CELL ELECTRODE MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL

摘要

An electrode for a fuel cell is provided with carbon nanotubes a fuel cell catalyst carried on the carbon nanotubes and an ionomer for coating the carbon nanotubes and the fuel cell catalyst. The length (La) and center to center pitch (Pa) satisfy the following two formulas: 30 ≤ La ≤ 240 and 0.351 × La + 75 ≤ Pa ≤ 250 where La [µm] is the length of the carbon nanotubes and Pa [nm] is the center to center pitch of the carbon nanotubes.
