ABSTRACT:
The fuel cell battery (10), comprising stacked modules (1) and using air and gaseous fuel as reactants, is arranged substantially axially symmetrically. A module comprises the following components: a three-layer, electrochemically active plate (2) which is free from holes and is composed of a solid electrolyte (20) conducting oxide ions as well as a gas and an air electrode (21 and 22); and a plate-shaped, metallic heat exchange element (5) for heating the reactants. According to the invention a porous layer (3) provides connection between the gas electrode (21) and the heat exchange element (5), the porous layer being electrically conductive and acting to equalize thermal stresses; this layer (3) forming further together with the electrochemically active plate (2) an integrated unit.
