Abstract
Recovery of dehydrogenation product must be done separately from supply of hydrogen fuel. However, there is a problem that it takes much time when dehydrogenation product recovery and fuel filling are done separately. A fuel filling/waste solution recovery apparatus includes measuring means to measure a volume of supplied fuel and a volume of recovered waste solution by measuring flow rates of solutions passing through a fuel filling nozzle and a recovery nozzle or piping, and a display which shows the volume of supplied fuel and the volume of recovered waste solution which are measured by the measuring means.
