Abstract
The present disclosure relates to a system for supplying hydrogen and a method for controlling the same. The system includes a hydrogen compressor for electrochemically compressing the hydrogen, and a controller that preliminarily drives the hydrogen compressor, estimates an amount of hydrogen transferred via a membrane electrode assembly interposed between an anode separator and a cathode separator in a cell of the hydrogen compressor in a period of the preliminary driving, and performs initialization driving to reduce moisture on a side of the anode separator of the cell based on the transferred amount of hydrogen being smaller than a threshold value.
Claims20
A system for supplying hydrogen, the system comprising:
- a hydrogen compressor configured to electrochemically compress the hydrogen, the hydrogen compressor having a cell that includes an anode separator, a cathode separator, and a membrane electrode assembly interposed between the anode separator and the cathode separator;
- and
- a controller configured to:
- preliminarily drive the hydrogen compressor during a preliminary driving period,
- estimate an amount of hydrogen transferred via the membrane electrode assembly during the preliminary driving period, and
- based on the transferred amount of hydrogen being less than a threshold value, perform initialization driving to thereby reduce moisture on a side of the anode separator of the cell.
A method for controlling a hydrogen supply system, the method comprising:
- preliminarily driving a hydrogen compressor using a reference voltage during a preliminary driving period;
- estimating an amount of hydrogen transferred via a membrane electrode assembly in a cell of the hydrogen compressor during the preliminary driving period;
- and
- performing initialization driving to reduce moisture on a side of an anode separator of the cell based on the transferred amount of hydrogen being less than a threshold value.
