WebSince SOFCs are operated at high temperature, expensive catalysts such as platinum or ruthenium are totally avoided [2, 6]. Also because of high-temperature operation, the SOFC has a better ability to tolerate the presence of impurities as a result of life increasing [6]. Costs are reduced for internal reforming of natural gas [6]. Web14 hours ago · Until a few years ago, the SOFC role was relegated to the provision of power in utility scale applications due to the significant time required to reach the operating temperatures. Nonetheless, the high working temperature allows to work not only with pure hydrogen but also with any king of rich hydrocarbon fuels such as natural gas or syngas.
