Proton-exchange membrane fuel cells (PEMFCs) have been widely developed because of its high efficiency, compactness and reduction of air pollutants emissions [1].While introducing fuel cell systems into the market, small scale hydrogen generation system from a common hydrocarbon feed stocks is required due to limited existing hydrogen infrastructures [2].Many types of fuel processing systems are being developed to supply a hydrogen rich gas for the operation of PEMFCs [3, 4, 5].
