摘要
A method is provided for increasing the life expectancy of a solid oxide fuel cell by preventing cathode poisoning due to chromium volatilization. Chromium hydroxide and oxyhydroxide formation and evaporation are prevented by continuously drying the cathode feed gas to low moisture levels. Power generation configurations that minimize the energy penalty associated with cathode gas drying are also disclosed.
