Optimization of Operating Condition for CO2 Facilitated Transport Membrane in Hydrogen Station

The hydrogen station in Japan is only 17 points though Toyota began to sell FCV from 15th November, 2014. The main reasons for which the spread of HS is late are a high construction cost and the indefinitely of spread prospect of FCV. However, it became clear that FCV in Japan spreads surely because the order for FCV exceeded 1000 from release in one week. The remaining problem is to reduce the cost of construction of 300 million yen. Therefore, we proposed membrane reactor composed of the reformer and the CO2 facilitated transport membrane to reduce the construction cost. It is necessary to achieve heat resistance of 160°C so that it is adopted for the membrane reactor. Therefore, we aim to optimize the operating condition (humidity, partial pressure of CO2 and differential pressure) of NDP to obtain the indicator of the heat resistance improvement at first. As a result, it is clear that the optimum operating condition of NDP is 80% of relative humidity, 200kPaG of the differential pressure and 40kPaG of the CO2 partial pressure.
