PROBLEM TO BE SOLVED: To provide a hydrogen gas filling method, and a hydrogen gas filling device capable of filling hydrogen gas collected in a collection vessel into a fuel tank of a hydrogen car after reducing the energy loss generated when hydrogen gas passes through a compressor.SOLUTION: Compressed hydrogen gas by a compressor 12 is stored in a storage vessel 36. Then, hydrogen gas stored in the storage vessel 36 is delivered and cooled. Then, a conduit located on the downstream side of a cooling means, and an apparatus provided on the conduit are cooled with the cooled hydrogen gas. The hydrogen gas used for cooling the conduit and the apparatus provided on the conduit is collected in the collection vessel 82. Thereafter, the hydrogen gas collected in the collection vessel 82 is filled into a fuel tank of a hydrogen car 19 without via the compressor 12 and the storage vessel 36. |
