Before, it was reported that intermittent pulsing voltage falls and continuous voltage falls were observed in the continuous operation of direct dimethyl-ether fuel cell. This time, the amount of gas humidification and the amount of catalysts that affect the performance of a fuel cell were changed, and the performance improvement in continuation operation was tried Consequently, the unstable performance was not improved by increasing anode steam from 107%RH to 139%RH. But, by increasing anode catalyst from 1.0mg/cm^2 to 4.0mg/cm^2, continuous voltage falls was improved by the increase in catalyst quantity. And, it was proven that the vaporizer of test equipment had produced intermittent pulsing voltage falls in the cause.
