Proton-exchange membrane fuel cells (PEMFCs) have been regarded as the new energy source for portable, stationary, and automotive applications. However, commercial exploitation of PEMFCs is still in an early stage, due to shortage of infrastructure in the society, high cost, and particularly the difficulty of the water/thermal management. One of the objectives of the current work is to analyze the water/thermal balances in a 100-kW class PEMFC system, consisting of PEMFC stack, compressor, intercooler, heater, humidifier, condenser, and radiator. As a first step, the heat and mass balances in the heat exchangers are analyzed for various water recovery schemes, followed by an analysis of the PEMFC stack effects on the system balance concerning the pressure drop and operating current density.
