Porous electrode substrate, membrane-electrode assembly using same, and polymer electrolyte fuel cell using same |
| abstract |
Disclosed herein is a porous electrode substrate in which carbon fibers are dispersed in the structure thereof have a fiber diameter of 3-15 micron and a fiber length of 2-30 mm, and are bound to one another by carbonized resin such that, when a pore distribution in the porous electrode is determined with a mercury intrusion porosimeter, such that a pore distribution curve is plotted on a graph having a common logarithmic scale on the horizontal axis, and a 1-100 micron pore diameter range of the pore distribution curve includes 80 or more measurement points at equal intervals along the common logarithmic scale, the pore distribution has a skewness S of −2.0<S<−0.8 and a kurtosis K of 3.5<K<10 in the 1-100 micron pore diameter range. |
