    • A low temperature proton exchange membrane fuel cell (PEMFC)system can be efficiently started even when the system is at a temperature near or below freezing (0°C). The cold start procedure is accomplished through heating the fuel cell by filling an anode chamber with fuel and generating hydrogen o the cathode chamber. The temperature by the exother on a cathode catalyst. Then and oxygen is supplied to the current flowing through saturation of the cathode wi the fuel cell without use of change membrane fuel cell (PEMFC) system can be the system is at a temperature near or t rt procedure is accomplished through heating the fuel ber with fuel (hydrogen or hydrogen-rich reactant gas) a cathode. A defined amount of oxygen is supplied to uel cell system is locally heated up to defined is chemical reaction between hydrogen and oxygen the hydrogen generation on the cathode is canceled cathode chamber in an amount sufficient to maintain n external load. This procedure provides plain saturation of the cathode with hydrogen and, as result, mild, safe and fast heating the fuel cell without use of additional external devices.
    • 即使系统处于接近或低于冰点(0℃)的温度,也可以有效地起动低温质子交换膜燃料电池(PEMFC)系统。 通过用燃料填充阳极室并在阴极室产生氢气来加热燃料电池来实现冷启动程序。 阴极催化剂上放热的温度。 然后,氧气被供给到流过阴极的电流,燃料电池不使用变化膜燃料电池(PEMFC)系统,系统可以在靠近或者室温的温度下通过加热燃料板来实现 燃料(氢或富氢反应气)阴极。 将定义量的氧气供给到电解槽系统中,局部加热至定义为氢和氧之间的化学反应,阴极上产生的氢气以足以维持n个外部负载的量被取消阴极室。 该方法提供阴极与氢气的平坦饱和,因此,温和,安全和快速地加热燃料电池而不使用额外的外部装置。
