Method for refueling hydrogen reservoir with buffered hydrogen to operate fuel cell for generating electrical driving power in e.g. motor car, involves outputting signal by control device when impurity concentration is above threshold value

摘要

The method involves detecting contamination values of hydrogen by a contamination sensor (15). The detected values are evaluated by a control device (16) that controls volumetric flow flowing to a hydrogen reservoir (7). Impurity concentration of substances in the hydrogen is reported to the control device. An acoustic and/or optical warning signal is not output by the control device during the impurity concentration is below a threshold value. The acoustic and/or optical warning signal is output by the control device when the impurity concentration is above the threshold value. An independent claim is also included for a device for carrying out a method for refueling a hydrogen reservoir with buffered hydrogen to operate a fuel cell.
