The device is more efficient than an internal combustion engine because reactants are directly converted into energy through a one-step electrochemical reaction. Fuel cells combined with water electrolyzers, which electrochemically split water into hydrogen and oxygen using renewable energy sources such as solar, mitigate global warming concerns with reduced carbon dioxide emissions. This collection of papers covers recent advancements in fuel cell technology aimed at reducing cost, improving performance, and extending durability, which are perceived as crucial for a successful commercialization. Almost all key materials, as well as their integration into a cell, are discussed: the bus plates that collect the electrical current, the gas diffusion medium that distributes the reactants over catalysts promoting faster reactions, and the membrane separating oxygen and hydrogen gases and closing the electrical circuit by transporting protons. Fuel cell operation below the freezing point of water and with impure reactant streams, which impacts durability, is also discussed. 517 $aProton Exchange Membrane Fuel Cells 606 $aIndustrial chemistry and chemical engineering$2bicssc 606 $aTechnology: general issues$2bicssc 610 $aasymmetric & 610 $aautomotive 610 $acarbon-free 610 $acatalyst layer 610 $acatalyst loading 610 $acathode 610 $acathode catalyst layer 610 $acomposite membranes 610 $acomputational fuel cell dynamics 610 $aconductivity limitation 610 $acontamination 610 $acurrent collector 610 $adead-ended anode (DEA) mode 610 $adiffusion limitation 610 $adurability 610 $aelectrolysers 610 $aelectrolyte 610 $aFreudenberg 610 $afuel cells 610 $afuel impurities 610 $agraphene thin film 610 $aI/C ratio 610 $aionomer thin film 610 $aISO concentration 610 $aisothermal water fill tests 610 $amembrane electrode assembly (MEA) 610 $amodule 610 $anitrogen dioxide 610 $aoxygen evolution 610 $aoxygen reduction 610 $aoxygen reduction reaction kinetics 610 $aoxygen transport resistance 610 $aPEM 610 $aPEM fuel cell 610 $aPEM water electorolyzer 610 $aPEMFCs 610 $aperformance 610 $aplatinum electrode 610 $aplatinum ionomer interface 610 $apolymer electrolyte fuel cell 610 $aporous structure 610 $aproton exchange membrane fuel cell 610 $aproton exchange membrane fuel cells 610 $arecovery 610 $aresponse surface method 610 $aSGL 29BC 610 $ashut-down and start-up process 610 $asubzero cold-starts 610 $asymmetric GDM 610 $aultralow-loaded anode catalyst layer 615 7$aIndustrial chemistry and chemical engineering 615 7$aTechnology: general issues 700 $aSt-Pierre$b Jean$4edt$01319339 702 $aDu$b Shangfeng$4edt 702 $aSt-Pierre$b Jean$4oth 702 $aDu$b Shangfeng$4oth 906 $aBOOK 912 $a9910566481103321 996 $aProton Exchange Membrane Fuel Cells (PEMFCs)$93033799 997 $aUNINA
