“…However, few publications on hydrogen pumps are available, and the characteristics of hydrogen pumps that separate hydrogen from a gas mix with low hydrogen concentration have been little studied [1,2]. In previous papers [3,4], we examined the performance of the hydrogen pump as a booster pump, and investigated the basic characteristics related to the separation and recovery of hydrogen from a gas mix.…”

SUMMARYThe proton exchange membrane fuel cell (PEMFC) cannot react 100% of fuel, because the cell potential becomes zero if all of the fuel is consumed in the PEMFC. Therefore, a small amount of fuel is always released from the PEMFC. The exhausted H 2 should be treated for safety. The V Cell −i ave characteristics were measured while varying the hydrogen concentration from 99.99% to 1%. In addition the V Cell of the constant voltage control was selected with reference to the measured V Cell −I ave characteristics. It was found that low-concentration hydrogen could be treated at V Cell = 0.15 to 0.3 V by the hydrogen pump and at V Cell = 0.4 to 0.6 V by PEMFC. The exhaust hydrogen concentration was reduced to several tens of ppm.
