SOLID OXIDE TYPE FUEL CELL-USE ELECTRODE SUPPORT SUBSTRATE AND PRODUCTION METHOD THEREFOR |
摘要 |
Disclosed is an electrode support substrate for a fuel cell which is even, gives a small fluctuation in gas permeability, and is capable of carrying out printing of an anodic electrode with high adhesiveness, and which comprises a ceramic sheet having a porosity of 20 to 50%, a thickness of 0.2 to 3 mm and a surface area of 50 cm<2> or more wherein the variation coefficient of measured values of the gas permeable amounts of areas measured by the method according to JIS K 6400 ranges from 5 to 20% and further the surface roughness measured with a laser optical manner three-dimensional shape measuring device may be 1.0 to 40 mu m as the maximum roughness depth (Rmax) thereof. <IMAGE> |
