燃料电池备用电源在通信基站的应用

对燃料电池备用电源进行了基站测试运行，包括在线式应用、离线式应用及长期稳定性测试，并依据氢气实际采购成本、氢气累计使用量、输出功率等，对燃料电池备用电源发电成本和发电效率进行了计算。测试结果表明：燃料电池备用电源可以基本满足通信基站应用要求，发电成本为6．96元／kWh，发电效率为43．1％。

Application of fuel cell backup power system in the communication base station

The fuel cell backup power system has been tested in a communication base station used as an online backup power supply and an offline emergency power supply. ＂]＇he experimental re suhs show that, the fuel cell backup power system can automatically start up as soon as commer cial power powers off to provide a continuous and stable power supply to the load of the base sta tion, and it can charge the battery pack in the station at the same time. Based on the cost of hy drogen, accumulative consumption and output power, the power generation cost and efficiency of the fuel cell power system are evaluated during the long-term test. And the power generation cost is 6.96yuan/kWh, and the efficiency of the fuel cell power system is 43.1%.
