Polymer Electrolyte Membrane Fuel Cells PEMFCs are the most appropriate type of fuel cells for application in vehicles due to their low operational temperature and high-power density. In this paper, a zero-dimensional, steady state thermodynamic modeling for an automotive 90kW PEMFC system has been built up in order to investigate the effects of operating parameters such as vehicle acceleration and operating pressure on the size of the system elements, heat and water system constitution, fuel consumption, and efficiency. Power output and power losses of the system were investigated at 3atm operation pressures. Hosseini, A. Shamekhi, A.

Research trends in proton exchange membrane fuel cells during 2008–2018: A bibliometric analysis

The parameters analyzed in the analysis were: type of document; the language of publication; volume and characteristics of publication output; publication by journals; performance of countries and research institutions; research trends and visibility. The analysis found that PEMFC studies have tended to be growing and that leading peer-reviewed journals have produced numerous publications on the subject. Followed by China ; Over the past five decades, studies of fuel cells as an energy source have intensified. Exchange membrane fuel cells have been mentioned in several ways in the research community [14]. A continuous and rapid increase in the number of publications can be observed, mainly since when more than papers on this technology have been published, demonstrating that this technology is currently a flourishing area of research in fuel cell technology. Most of the studies in this field PEMFC have been carried out in different countries of the world, with the most significant number of reports coming from China and the United States [15].

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel often hydrogen and an oxidizing agent often oxygen [1] into electricity through a pair of redox reactions. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in The first commercial use of fuel cells came more than a century later following the invention of the hydrogen—oxygen fuel cell by Francis Thomas Bacon in The alkaline fuel cell , also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mids to generate power for satellites and space capsules.

Fuel Cell Technology pp Cite as. PEM fuel cells use a proton conductive polymer membrane as electrolyte. 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 demonstrated in almost any conceivable application, from powering a cell phone to a locomotive.

Demand for fuel cell technology is growing rapidly. Fuel cells are being commercialized to provide power to buildings like hospitals and schools, to replace batteries in portable electronic devices, and as replacements for internal combustion engines in vehicles. PEM Proton Exchange Membrane fuel cells are lighter, smaller, and more efficient than other types of fuel cell. This new edition of Dr. Yet it now also provides invaluable information on the latest advances in modeling, diagnostics, materials, and components, along with an updated chapter on the evolving applications areas wherein PEM cells are being deployed.

Platinum Metals Rev. Proton exchange membrane fuel cells PEMFCs dominate the transportation fuel cell market and platinum Pt is the catalyst material used for both anode and cathode. This review sets out the fundamentals of activity, selectivity, stability and poisoning resistance which make Pt or its alloys the best available materials to use in this application. It is clear that Pt is the only element which can meet the requirements for performance while avoiding slow reaction kinetics, proton exchange membrane PEM system degradation due to hydrogen peroxide H 2 O 2 formation and catalyst degradation due to metal leaching. Some of the means by which the performance of Pt can be enhanced are also discussed. A PEMFC is a device that electrochemically reacts hydrogen H 2 with oxygen O 2 to produce electricity with water as the only by-product.
