FUEL-CELL POROUS SEPARATOR, FUEL CELL, AND METHOD FOR MANUFACTURING FUEL-CELL POROUS SEPARATOR

摘要

A fuel-cell porous separator according to the present invention is formed of a composition including a resin material and a carbonaceous material, wherein the content of the carbonaceous material accounts for 80-95 mass% of the total mass of the carbonaceous material and the resin material, and fine pores with a fine-pore diameter of 1.5-4.0 μm account for 90 vol% or more in a fine-pore distribution of the fuel-cell porous separator as measured by the mercury intrusion method.
