Fuel cell/battery (FCB) systems are promising power generation/energy storage systems because of their bi-functionality as fuel cells and as secondary batteries. From the current research, it was found that MnOOH formed via the electrochemical discharge of manganese dioxide (MnO2) and that the oxyhydroxide can be chemically transformed back to MnO2 with gaseous oxygen (O2). The recharged MnO2 can be used as the cathode in a fuel cell with an O2 supply and it can also be electrochemically discharged without an O2 supply. This study suggest that the FCB system can be constructed using MnO2 as the cathode and a metal hydride as the anode, which can be rapidly charged to more than 70% of the theoretical capacity within 10 min using pressurized H2 and electrochemically discharged. Furthermore, a novel fibrous MnO2 electrode for FCB system was fabricated on carbon fiber by the electrodeposition method in order to improve contact area between MnO2 and the electrical conducting material.

燃料电池/电池(FCB)系统具有燃料电池和二次电池的双重功能，是一种很有前途的发电/储能系统。目前的研究发现，MnOOH是通过二氧化锰(MnO2)的电化学放电形成的，氢氧化锰可以在气态氧(O2)的作用下化学转化为MnO2。充电后的MnO2可以用作有氧气供应的燃料电池的阴极，也可以在没有氧气供应的情况下进行电化学放电。研究表明，以MnO_2为正极，金属氢化物为负极，用加压氢气在10min内快速充电至理论容量的70%以上，并进行电化学放电，可构成FCB体系。此外，为了提高MnO2与导电材料的接触面积，采用电沉积法在碳纤维上制备了一种用于FCB系统的纤维状MnO2电极。
