燃料电池及其在冷热电联供系统中的应用

分析了燃料电池的原理和主要特点，认为磷酸燃料电池(PAFC)是目前技术最成熟、商业化程度最高的民用燃料电池；焙融碳酸盐燃料电池(MCFC)、固体氧化物燃料电池(SOFC)和质子交换膜燃料电池(PEMFC)是最有希望的商业化的燃料电池，以上燃料电池以热电联户方式运行时总效率可达80%以上，又环境污染小。简要介绍了燃料电池的冷热电联供系统的流程及工程应用。

Fuel cell and its application to the combined cooling heating and power system

Analyses the principles and main characteristics of fuel cell. Considers that phosphoric acid fuel cell(PAFC)is the ripest in technique and most commercialized civil fuel cell. Molten carbonate fuel cell(MCFC),solid oxide fuel cell(SOFC)and proton exchange membrane fuel cell(PEMFC)are the most promising commercial fuel cells. Points out that the total efficiency of these cells is up to above 80% while operating in cogeneration of heat and power. The fuel cells are environment friendly and have lower noise level when working. Presents the process flow of fuel cell and some projects operated in the conbimed cooling, heating and power system.
