Patent ID: 8307863

Claim:
A fuel filling/waste solution recovery apparatus which supplies a hydrogen storage material to a fuel vessel of a machine fueled by hydrogen generated by dehydrogenation of a hydrogen storage material and recovers waste solution derived from dehydrogenation from a waste solution vessel, comprising: a fuel filling nozzle and a waste solution recovery nozzle; measuring means to measure a volume of the waste solution, analyzing means installed in the recovery nozzle for analyzing a concentration ratio of the dehydrogenation product and hydride in the waste solution which flow through the recovery nozzle; a database storing a hydride unit price and a dehydrogenation product unit price; and calculating means for calculating a waste solution price based on the volume of the waste solution measured by the measuring means, the hydride unit price and dehydrogenation product unit price stored in the database and a concentration ratio of the waste solution analyzed by the analyzing means.
