Hydrogen of hydrogen station for FCV is usually produced by the reforming reaction, followed by the water gas shift reaction. The reformed gas contains a large amount of CO2, and this decreases the power efficiency although it does not influence the PEFC performance. The CO2removal technology from the reformed gas is an important factor to improve the FCV performance. We developed a membrane for selective CO2separation containing carbonate salt as a CO2carrier. The support material of the CO2carrier for a selective CO2separation membrane should have water solubility, mechanical strength and heat resistance. We evaluated three support materials, PVA, AQN and NDP. The PVA membrane was broken at high temperature region though it showed good CO2permeance at low temperature region. The AQN membrane had low CO2permeance in all temperature regions. Although the NDP membrane had CO2permeance at high temperature region, it should be improved further to increase the CO2permeance. |
