Elektrochemischer Generator mit modifizierten Brennstoffelektroden für die Verwendung mit Kohlenwasserstoffbrennstoffen.

摘要

An electrochemical generator apparatus (30) is constructed containing one or more electrochemical cells (10), the cells containing a porous fuel electrode (18), a porous air electrode (14), and solid oxide electrolyte (16) disposed therebetween, where the fuel electrode is impregnated with metal-containing chemicals which form metal oxides upon heating, where the metal is selected from the group consisting of Mg, Ca plus Al, Sr plus Al, Zr, Y, Ce, and their mixtures; and where these electrochemical cells are contacted with a hydrocarbon fuel gas and operated at over 800 DEG C, and where the metal oxides are effective in preventing cell deterioration due to carbon deposition from the hydrocarbon fuel.
