Abstract
Molten carbonate fuel cell configurations are provided that include one or more baffle structures within the cathode gas collection volume. The baffle structures can reduce the unblocked flow cross-section of the cathode gas collection volume by 10% to 80%. It has been discovered that when operating a molten carbonate fuel cell under conditions for elevated CO2 utilization, the presence of baffles can provide an unexpected benefit in the form of providing increased transference and/or increased operating voltage.
