Attention on the hydrogen station has increased owing to the commercialization of fuel cell car near future. Among several production schemes of hydrogen, the steam reforming technology with water gas shift reaction is used most widely. Despite of a lot of studies on steam reforming system [1-2], it is still necessary to design more efficient steam reforming system for the hydrogen station. The present study is conducted to give an insight for optimal design of 30 Nm~3/h hydrogen station which has the steam methane reforming process as shown in Fig. 1.
