Abstract
Polymer electrolyte membrane fuel cell (PEMFC) is a viable energy candidate that can be used to replace fossil resources. This paper presents the waste heat recovery in PEMFC using Organic Rankine Cycle (ORC) simulated using MATLAB/SIMULINK platform. R245fa is the working fluid used for recovery of waste heat. The steady state power output of a 100-cell stack is utilized for heat recovery. The maximum power point of the stack at 30 A and 0.41 V is considered for the calculation of net efficiency, after heat recovery. After the simulation, the combined system’s efficiency increased by 29.5%.
