  • Publication number: 20140167705
    Abstract: A method of charging a battery includes following steps: First, a charging voltage is provided to charge the battery. Afterward, a charging control variable is judged whether to reach to an adjustment value. Afterward, the charging voltage is adjusted with a first voltage difference to continuously charge the battery when the charging control variable reaches to the adjustment value. Afterward, a health state value of the battery is judged whether less than or equal to a critical health state value. Finally, the charging voltage is increased with a second voltage difference to continuously charge the battery when the health state value of the battery is less than or equal to the critical health state value.

  • Patent number: 7855029
    Abstract: A fuel cell module includes an anode flow board, a cathode board, an intermediate adhesive layer, a membrane electrode assembly (MEA) including a membrane edge, and a leak-proof adhesive layer mounted on the membrane edge, thereby preventing contact between the intermediate adhesive layer and the membrane edge. The adhesive ability of the leak-proof adhesive layer to the membrane edge is higher than that of the intermediate adhesive layer to the membrane edge. Therefore, the methanol leakage from the membrane can be avoided.
