A cermet electrode and a method of manufacturing the same

摘要

The invention relates to a cermet electrode for use as e.g. the fuel electrode of a solid electrolyte fuel cell and a method of manufacturing the same. This cermet electrode is characterized by comprising grains of a high-melting metal having a melting point of not less than 1,900 DEG C and/or grains of an alloy containing the high-melting metal and secured in position by zirconia doped to present the form of a cubic lattice. The method of manufacturing this cermet electrode comprises covering a support of doped zirconia with grains of a high-melting metal having a melting point of not less than 1,900 DEG C and/or grains of an alloy containing the high-melting metal and causing a framework structure to grow from the doped zirconia around the grains by electrochemical vapor deposition to secure the grains in position and to the support. The cermet electrode of the invention is very satisfactory not only in useful life and electrode activity but also in electrical conductivity.
