The direct carbon fuel cells(DCFC) are power generation devices which transform chemical energy into electric power directly in electro-chemical reaction between carbon fuel and air
the energy thransformation efficiency of DCFC can reach more than 80%.Based on different electrolytes
DCFC can be divided into molten hydrate DCFC
molten carbonate DCFC
and solid oxide DCFC etc..The working principle and performance of different DCFC have been expounded
and the factors which may affect the performance of DCFC being analysed
at the same time
some representative cell structure of DCFC and status quo of research being presented.
