Carbon Corrosion in PEM Fuel Cell Dead-Ended Anode Operations

This paper investigates the effects of dead-ended anode (DEA) operation on the electrode carbon corrosion of the Proton Exchange Membrane (PEM) fuel cell. A reduced order isothermal model is developed focusing on the species concentration along the channel and associated membrane phase potential. This model explains, and can be used to quantify, the carbon corrosion behavior during DEA operatio...

Dynamics of Autohumidifed PEM Fuel Cell Operation

Start-up and dynamic responses to changes in load are reported for a dry feed, autohumidified polymer electrolyte membrane fuel cell PEMFC . The fuel cell current can be ignited by water injection; criteria are derived for the required water injection as functions of fuel cell size, temperature, and reactant feed rates. Steady-state multiplicity is observed where the fuel cell current can be ei...
