Abstract

The output power of the MCFC stack was 217.6 W under reaction gas pressure, 0.9 MPa/cm² and utilization of oxidant and fuel gas, 20%. By calculation it was demonstrated that the heat balance state in the stack was kept at 300 mA/cm² under the utilization of fuel gas and oxidant,20%. The current density in heat balance state was higher than 100 mA/cm² under the utilization of air+CO₂ mixture gas as oxidant and H₂+CO₂ mixture gas as fuel gas,40% and 60% respectively. If the utilization was increased in the stack, the current density in heat balance state would be lowered. If the output power of the stack was increased, the thermal-electrical efficiency would be decreased and if reaction gas pressure was increased, the thermal-electrical efficiency would be increased.
