A control-oriented mathematical model of a polymer electrolyte membrane (PEM) fuel cell stack is developed and experimentally verified. The model predicts the bulk fuel cell transient temperature and voltage as a function of the current drawn and the inlet coolant conditions. The model enables thermal control synthesis and optimization and can be used for estimating the transient system perform...

Fuel cells (FCs) have gained a prominent position in recent years within the scientific community and energy market as an alternative to mitigate inherent problems production based on fossil fuels such constant reduction of nonrenewable resources, greenhouse gas emissions, climate change. The versatility high temperature (HT) proton exchange membrane (PEM) FCs, together with their efficiency po...

The present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. Various methods of hydrogen production for automotive applications have been discussed first. As the hydrogen production is one of the major challenges for application of proton exchange membrane (PEM) fuel cells, especially in vehicular indus...

Abstract Water management is a critical challenge in low temperature (LT) Proton Exchange Membrane Fuel Cells (PEM FC); condensed liquid appears mainly at the cathode side, where water from reduction reaction generated. Differences concentration may result transfer of to anode side across membrane electrode assembly (MEA). Excessive can negatively affect fuel cell performance, causing efficienc...

In the proton exchange membrane fuel cell, (PEM) serves as both main conductor of protons and fuel-blocking membrane. Thus, high conductivity excellent stability are expected for PEMs at same time. According to chemical structure, this review divides PEM into three groups. Recently, high-performance has been made possible by controlling organic–inorganic hybrid composite membranes, nanofiber me...
