High temperature proton exchange membrane fuel cells (HT-PEMFC) have
attracted great interests in recent years due to their advantages compared with
common PEMFC. PEM fuel cells based on perfluorinated membrane electrolytes
operate in the temperature range between 60 and 80°C while elevating the operating
temperature (up to 200°C) provide improved carbon monoxide tolerance, faster
electrode kinetics, simpler thermal and water management and more efficient
recovery of waste heat as a practical energy source. In this investigation the drivers
behind the interest in HT-PEMFCs and the challenges in developing novel materials
for membranes preparation is reviewed. Also a brief analysis of temperature
requirements for CO tolerance is presented. The research shows an exhaustive
presentation and comparative discussions on various types of high temperature
membranes. Finally, the importance of porosity in electrodes for HT-PEM has been
studied.
