Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift reactor with a hydrogenseparating palladium membrane is modeled in the COMSOL Multiphysics® Chemical Engineering Module.
