Abstract:
1. A method for measuring remaining hydrogen capacity of hydrogen storage canister by applying tag information, wherein at least one hydrogen storage canister is provided for supplying hydrogen to support a reaction in an application device, the hydrogen storage canister comprising an information identification tag, which stores at least one record of tag information indicating a hydrogen storage quantity of the hydrogen storage canister, the method comprising following steps: (a) reading the tag information from the information identification tag; (b) detecting a hydrogen consumption quantity supplied from the hydrogen storage canister; (c) subtracting the hydrogen consumption quantity from the hydrogen storage quantity to calculate a residual hydrogen quantity; (cl) detecting a hydrogen storage pressure of the hydrogen storage canister; (c2) determining if the hydrogen storage pressure is lower than a preset hydrogen pressure threshold; (c3) determining if the residual hydrogen quantity is lower than a preset hydrogen residue threshold, when the hydrogen storage pressure is lower than the hydrogen pressure threshold, for determination of correctness of the residual hydrogen quantity; (c4) issuing an alarm when the residual hydrogen quantity is higher than the hydrogen residue threshold but the hydrogen storage pressure is lower than the hydrogen pressure threshold; and (d) updating the tag information of the information identification tag by replacing the tag information with the residual hydrogen quantity so calculated.
