Operation of Molten Carbonate Fuel Cells With Enhanced CO2 Utilization

Molten carbonate fuel cells (MCFCs) are operated to provide enhanced COutilization. This can increase the effective amount of carbonate ion transport that is achieved. The enhanced COutilization is enabled in part by operating an MCFC under conditions that cause transport of alternative ions across the electrolyte. The amount of alternative ion transport that occurs during enhanced COutilization can be mitigated by using a more acidic electrolyte.
