Demand for this technology is growing rapidly. Fuel cells are being commercialized for stationary and portable electricity generation, and as a replacement for internal combustion engines in automobiles. Proton Exchange Membrane (PEM) fuel cells in particular are experiencing an upsurge. They have high power density and can vary their output quickly to meet shifts in power demand. 410 0$aSustainable world series. 606 $aFuel cells 606 $aIon-permeable membranes 615 0$aFuel cells. 615 0$aIon-permeable membranes. 676 $a621.312429 700 $aBarbir$b Frano$f1954-$0627279 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910817461303321 996 $aPEM fuel cells$91213199 997 $aUNINA
