We considering cost down of hydrogen stations in order to spread fuel cell vehicles. The PSA device included in the hydrogen station to occupies 30% of the construction cost. Therefore, we proposed the cost down by replacing the PSA and CO shift converter with a membrane reactor composed of CO₂ facilitated transport membrane and CO shift converter. We aim to enhance the membrane performance by keeping water in the membrane. Therefore, we added graphite as porous materials and silica gel as water absorption grains to the membrane. However, Graphite has water repellency. Hence, it is necessary to modify surface of graphite with surfactants AcetyrenolE00. As a result, we found the optimum amount of graphite and silica gel in experiments.
