Title:
SUPPORTING CARBON MATERIAL FOR SOLID POLYMER FUEL CELL AND CATALYST METAL PARTICLE-SUPPORTING CARBON MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/141810
Kind Code:
A1
Abstract:
Provided are: a supporting carbon material for a solid polymer fuel cell, said supporting carbon material making it possible to produce a high-performance solid polymer fuel cell in which there is little decrease in power generation performance as a result of repeated battery load fluctuation that inevitably occurs during operation of the solid polymer fuel cell; and a catalyst metal particle-supporting carbon material. The present invention relates to: a supporting carbon material for a solid polymer fuel cell, said supporting carbon material being a porous carbon material in which the specific surface area of mesopores having a pore diameter of 2-50 nm according to nitrogen adsorption measurement is 600-1,600 m2/g, the relative intensity ratio (IG'/IG) of the peak intensity (IG') of the G-band 2,650-2,700 cm-1 range to the peak intensity (IG) of the G-band 1,550-1,650 cm-1 range in the Raman spectrum is 0.8-2.2, and the peak position of the G'-band is 2,660-2,670 cm-1; and a catalyst metal particle-supporting carbon material.
