| Research Abstract |
For the demand of high pressure hydrogen gas, a noble electrochemical hydrogen pump was designed and fabricated, which has internal humidifier and dead-end at anode channel to reduce system cost. The pump was successfully operated up to 2 MPa, and evaluated on the voltage and current efficiency with electrochemical measurement. The maximum values of voltage, current and total efficiency were 54, 96 and 45 %, respectively. The total efficiency obtained is same as that of conventional mechanical compressors, suggesting the advantage ofelectrochemical hydrogen pumps
