Abstract

PURPOSE: To facilitate work, improve durability, and obtain an excellent power generating characteristic by forming a separator of heat resistant alloy, coating its surface with conductive ceramics, and using the separator obtained by heating it in an oxygen existent atmosphere. CONSTITUTION: A separator 3 is formed in a shape having grooves out of heat resistant alloy mainly composed of chrome and nickel. Next, a surface of this heat resistant alloy is coated, for example, with lanthanum La type (such as LaMnO3 , LaCrO3 and LaC0 O3 ) conductive ceramics by an detonation flame spraying method or an electron beam evaporation method or the like. Afterwards, it is heated, for example, for 1 to 4 hours at a heating temperature of 1100 to 1200 deg.C in the atmosphere. A required process is only to perform it in an oxygen existent atmosphere without limiting to the inside of the atmosphere. By performing in this way, a thermal expansion difference is normally large between a ceramic layer and a metallic layer, and separation is easily caused, but when they are heated in the atmosphere, a part of the metallic layer is oxidized, and since a reaction layer is formed between it and the ceramic layer, separation can be restrained. Excellent power generating performance is obtained, and durability is improved.
