high temperature fuel cell
In contrast to low-temperature fuel cells, high-temperature fuel cells operate at working temperatures of 600 °C to 1,000 °C.
High-temperature fuel cells are suitable for stationary use in buildings. Since they generate electrical and thermal energy, the waste heat can be used for heating purposes or for cogeneration. High-temperature fuel cells have a catalyst made of simple metal and can also be operated with natural gas. They are therefore less expensive and have better energy utilization. Their efficiency is over 60 %, far higher than that of low-temperature fuel cells, which is around 50 %.
High-temperature fuel cells include the molten carbonate fuel cell( MCFC), the solid oxide fuel cell( SOFC) and the solid oxide fuel cell.
