Elevated Pressure Operation Of Molten Carbonate Fuel Cells With Enhanced CO2 Utilization

摘要

Molten carbonate fuel cells (MCFCs) are operated at elevated pressure to provide increased operating voltage and/or enhanced CO₂ utilization with a cathode input stream having a low CO₂ content. It has been discovered that increasing the operating pressure of a molten carbonate fuel cell when using a low CO₂-content cathode input stream can provide unexpectedly large increases in operating voltage while also reducing or minimizing the amount of alternative ion transport and/or enhancing CO₂ utilization.
