Abstract:

An organic Rankine cycle (ORC) with R245fa/R123 zeotropic mixture as cooling system to recover the waste heat of proton exchange membrane fuel cell (PEMFC) was proposed to improve the energy utilization factor. An ORC hybrid system was established using Aspen Plus software. The influence of the mass fraction of zeotropic fluids R245fa on ORC system performance was analyzed by fixing the condensing temperature and pressure etc. The results show that R245fa/R123 with mixing ratio of 0.6 / 0.4 has the highest waste heat recovery at winter and 101.3 kPa at fixed condensation pressure, which are 10.90% and 11.08%, respectively. Zeotropic mixtures have better working condition adaptability than pure components. By adjusting the mixing ratio, the waste heat of PEMFC can be fully recovered under different working conditions.

Key words: proton exchange membrane fuel cell (PEMFC), zeotropic mixture, organic Rankine cycle(ORC), condensation conditions
