The calculated results are summarized in Table 2 to evaluate the effects of the C02 separation. The results shows the system efficiency increases from 58% to 63% by using the C02 separator. The considerable improvement of fuel utilization from 82% to 93.6% has greater effect on the enhancement of system efficiency than the extent of reduction of the excess power generation of the expander-compressor. The reduction of power generated in the expander-compressor is mainly due to the compression work for COi which is transferred from the anode exhaust to the oxidant stream.
