摘要
燃料电池是将燃料的化学能通过电化学反应直接转化为电能的电化学发电装置.通过将高温燃料电池的排气作为吸收式制冷机的驱动热源,提出了一个由高温燃料电池(MCFC)和吸收式制冷机等组成的冷热电联产系统,该系统在提供电能的同时,还可为建筑物等用户夏季供冷和冬季供热.该系统的能量和平衡分析结果表明系统总的燃料利用率可达86%以上,损失最大值发生在燃料电池子系统.
Fuel cells are energy conversion devices that can directly convert chemical energy from fuels into electricity. A cogeneration system made up of the high temperature fuel cell and the absorption refrigeration was proposed by using the waste gas exhausted from the high temperature fuel cells to drive the absorption refrigeration. In addition to supplying electricity, this system can also provide a large building with aironditioning in suiraner and heating in winter. Results of the energy and exergy balance analysis of the system show that the overall fuel ulilization efliciency of the proposed cogeneration system is more than 86%, and the largest exergy loss is generated in the fuel cell.
