Online diagnosis of PEM Fuel Cell
2008 13th International Power Electronics and Motion Control Conference, 2008This study consists on online detection of fuel cell dysfunction in embedded applications without additional hardware component. The power converter usually coupled with the fuel cell is used to perform the diagnosis strategy. The main interest of the method presented in this paper is to simultaneously optimize the performances, the cost and the size ...

Dynamic Characteristics of PEM Fuel Cells
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006Fuel cell applications have become increasingly attractive. Therefore, comprehensive models, simulation and analysis tools are required to characterize fuel cell behavior. For years, the focus has been on describing the steady state characteristics of fuel cells, which is an important application but certainly not the only one.

Development of a PEM fuel cell vehicle
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002This paper describes the development of a proton exchange membrane (PEM) fuel cell powered vehicle. The vehicle is a converted Suburban with a series hybrid electric configuration. The auxiliary power unit is a PEM fuel cell that is used to power the vehicle and charge the batteries when cruising. System requirements and design decisions are presented.

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 ...
