Fuel-cell systems operable in multiple modes for variable processing of feedstock materials and associated devices, systems, and methods

摘要: Fuel cells for selectively reacting a feedstock material with or without generating electricity, and associated systems methods are disclosed. A fuel cell system in accordance particular embodiment includes first electrode positioned region, second an ion-transport medium between the regions, electrical circuit connected electrodes. The is operable mode to react by non-electricity-generating reaction produce product electricity-generating electricity. controller receives input (e.g., corresponding change demand electricity) causes switch operating response input.
