Anew structure type fuel reformer proposed by investigator was developed in this research. The reactor consists of stuck of units having plates for fuel reforming catalyst, hydrogen membrane and hydrogen recovery. The research discussed for the demonstration of the fuel reforming concept experimentally, and also a new type hydrogen membrane having high performance.The proposed reformer is different from conventional packed bed type reformer, and removes produced hydrogen from reaction surface of the plate catalyst via a hydrogen permeation membrane. The plate type reformer has merits of high-hydrogen productivity, reduction of reforming temperature by using the hydrogen membrane, and also homogeneous temperature distribution in reforming catalyst plate, compactness of the rector. The research approaches the demonstration from three stand points of plate-type reactor reforming experiment, numerical analysis of the reformer and a hydrogen permeation membrane development.Single unit of re … More former having a reforming catalyst, hydrogen permeation membrane and hydrogen recovery channel was prepared for the reforming demonstration. Methanol and methane were used reforming fuel. Reforming rate, hydrogen permeation rate, temperature distribution were measured. In the methanol reforming, reforming temperature reduction of 20-50 degree C. and hydrogen yield increase of 15 % was demonstrated. In the methanol reforming, reforming temperatures were reduced from 700-800 deg. C to 450-600 deg. C. The hydrogen yield was increased from 62 % to 80 % at 620 deg. C., and also from 80 % to 94 % at 480 deg. C. The reforming performance showed the possibility of the reformer. New method of hydrogen permeation membrane was examined in this research. Palladium (Pd) alloys is conventional material for the membrane. However, it is quite expensive like gold, and is required to be reduced usage amount for the membrane. Generally, the Pd membrane needs a thickness more than 20 micro m to keep the hardness. In this study, a new Pd alloy membrane having thickness of less 5 micro m, which was supported by another metal material membrane, was developed. The developed membrane performance for hydrogen permeation was demonstrated experimentally. The membrane has higher hydrogen permeability per Pd alloy mass compared with conventional Pd alloy membrane was demonstrated. This research demonstrated the possibility of the proposed plate-type reformer. Less
