G111 Study of a Fuel Cell Vehicle with an Ammonia Onboard Dissociator : 3^<rd> Report; Ammonia Circulation System for Residual Ammonia after Dissociation

Based on the first and second report, the residual ammonia circulation system is constructed with the system of the separator and the distiller. The ammonia gas can be dissociated to hydrogen, nitrogen and residual ammonia through the catalyst in the dissociator. The residual ammonia by 13ppm or more causes decrease of the output of fuel cells. In order to separate residual ammonia, it is sent to the separator that uses the fact that ammonia well in water. Water with high concentration of ammonia is divided to ammonia gas and water in the ammonia distiller. Thereby, the circulation system for the residual ammonia can be constructed.
