1课题背景高温燃料电池可与燃气轮机、蒸汽轮机等动力装置组成多重循环,实现能量的梯级利用,从整体上进一步提高能源利用率,为总能系统的发展提供了新的可行途径.氢能是一种高效、清洁、可再生的二次能源,被称为21世纪的能源.研究以氢为燃料、由高温燃料电池、燃气...“,”With the combination of chemical looping combustor and solid oxide fuel cell (SOFC), a new kind of combined cycle Solid Oxide Fuel Cell Power Generation System with Chemical Looping Combustor is proposed. By using chemical looping combustor, this new cycle is capable of working at higher temperature and pressure. Fuel and oxidizer of fuel cell can be preheated to SOFC working temperature by chemical looping combustor instead of by fuel cell exhaust gas via a series of high temperature heat exchangers. Thus the exergy losses caused by heat transfer and the problem related with high temperature gas-gas heat exchangers can be avoided. Theoretical analysis shows that this new cycle can attain higher efficiency. Also it is environmental friendly.
