A fuel cell-use electrode support substrate comprising a ceramic sheet having a porosity of 20-50%, a thickness of 0.2-3 mm and a+ surface area of at least 50 cm2, wherein a coefficient of variation of a measured air passage volume in a region measured by a JIS K 6400-compliant method falls within 5-20%, or, in addition, a surface roughness at a maximum roughness depth (Rmax) measured by a laser optical three-dimensional shape measuring device is 1.0-40 µm, whereby the support substrate is homogenous and small in fluctuation of gas permeability, and can perform an anode electrode printing with a very close contact.

L'invention concerne un substrat support d'électrode utilisé comme pile à combustible et comprenant une feuille céramique d'une porosité de 20-50 %, une épaisseur de 0,2-3 mm et une zone superficielle d'au moins 50 cm?2¿. Un coefficient de variation d'un volume de passage d'air mesuré dans une zone mesurée par un procédé adéquat se situe dans les limites de 5-20 % ou, en plus, une rugosité superficiellle d'une profondeur maximale de rugosité (Rmax) mesurée par un dispositif de mesure de forme tridimensionnelle optique laser est 1,0-40 .gamma.m. Le substrat support est homogène et petit en termes de fluctuation de perméabilité de gaz, et peut réaliser une impression d'électrode anode avec un très proche contact.
