CARBON SHEET, AND GAS DIFFUSION ELECTRODE SUBSTRATE, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL USING SAME
A carbon sheet comprising at least a carbon fiber structure comprising carbon fibers, a binder, and graphite particles, the carbon sheet being characterized in that in the pore diameter distribution of the carbon sheet, the ratio of the volume of a second peak present in a region having a pore diameter of 0.5-3 [mu] m (inclusive) to the volume of a first peak present in a region having a pore diameter of 20-100 [mu] m (inclusive) is 0.06-0.50. The purpose of the present invention is to provide a carbon sheet which exhibits high power generation performance in a solid polymer fuel cell, suppresses dry-up, and has both conductivity and moisture retention.
一种碳片材，其至少包含由碳纤维形成的碳纤维结构体、粘合材料和石墨粒子，其中，在碳片材的孔径分布中，在孔径为0.5μm以上且3μm以下的区域存在的第二峰容积相对于在孔径为20μm以上且100μm以下的区域存在的第一峰容积的比值为0.06～0.50。为了在固体高分子型燃料电池中发挥高的发电性能，提供抑制干涸的、兼顾导电性和保湿性的碳片材。
