PEM Fuel Cells: A Mathematical Overview
SIAM Journal on Applied Mathematics, 2009We present an overview of the mathematical issues that arise in the modeling of polymer electrolyte membrane fuel cells. These issues range from nanoscale modeling of network structures arising in pore formation within the polymer and the formation of nanostructured agglomerates within the catalyst layer, to macroscale models of multiphase flow and ...

On Parameterizing PEM Fuel Cell Models
2019 American Control Conference (ACC), 2019A methodology for parameterizing polymer electrolyte membrane (PEM) fuel cell models is presented. The procedure starts by optimal experimental design (OED) for parameter identification. This is done by exploring output sensitivities to parameter variations in the space of operating conditions. Once the optimal operating conditions are determined, they

Minimum Fuel Consumption Strategy for PEM Fuel Cells
IEEE Transactions on Industrial Electronics, 2009This paper proposes a proton exchange membrane fuel cell control strategy to produce the power requested by an electrical load, minimizing the fuel consumption and also providing a regulated DC bus voltage to the load. The power system consists of a hybrid fuel cell/capacitor topology, and the control objective is to follow the minimum fuel consumption

Fuel flow control of a PEM Fuel Cell with MPPT
2012 IEEE International Symposium on Intelligent Control, 2012In this paper, a Fuel Cell (FC) Maximum Power Point Tracking (MPPT) with fuel flow optimization is developed. The aim of this study is to extract the maximum power from a FC at different fuel flow rates and to protect the FC from over-current and voltage collapses across terminals.

PEM fuel cells use a proton conductive polymer membrane as electrolyte. PEM stands for Polymer Electrolyte Membrane or Proton Exchange Membrane. Sometimes they are also called polymer membrane fuel cells, or just membrane fuel cells. This technology has drawn the most attention because of its simplicity, viability, quick start-up, and it has been ...

Electrocatalysts for PEM Fuel Cells
Advanced Energy Materials, 2018AbstractDegradation phenomena of electrocatalysts for proton‐exchange membrane fuel cells and their mechanisms are reviewed. Platinum dissolution and redeposition, carbon‐support corrosion, inhomogeneity during start‐up and cell reversal are discussed as factors that influence the degradation of electrocatalysts with relation to electrode potential ...

A fuel cell is an electrochemical device that continuously and directly converts the chemical energy of externally supplied fuel and oxidant to electrical energy. Fuel cells are customarily classified according to the electrolyte employed. The five most common technologies are polymer electrolyte membrane fuel cells (PEM fuel cells or PEMFCs), alkaline
