ABSTRACT:
A layered sintered body for an electrochemical cell which is a planar-type layered sintered body composed of an electrode and a separator stacked thereon, wherein a plurality of gas flow passages are formed by coupling grooves formed on the electrode and the separator. Even when this electrochemical cell is subjected to repetition of a cooling-heating cycle, an increase of internal resistance on and around the boundary between the separator and electrode can be restrained and layer separation and development of cracks at the joint boundary can be prevented.
