Abstract

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) have received substantial attention in stationary sector applications, due to their high carbon monoxide (CO) tolerance, high-quality waste heat and simplified water management system. Hydrogen rich gas produced in a fuel reforming process can be used and can be directly supplied to the HT-PEMFC stack anode omitting complex hydrogen purification process. It allows a wide range of fuel flexibility for the reforming process. The present study is an analysis of HT-PEMFC stack performance operating with an integrated steam reformer, operated with various fuels like ethanol, glycerol, methanol, methane and other fuels. The HT-PEMFC stack is modelled with a concept of varying local current density in the cathode catalyst layer. (C) 2016 Elsevier Ltd. All rights reserved.
