Abstract

Oppfinnelsen vedrører membranelektrodeenheter for elektrolyse av vann (elektrolyse MEA'er), som inneholder: en ioneledende membran som har en forside og en bakside; et første katalysatorlag på den fremre siden; et første gassdistribusjonssubstrat på den fremre siden; et andre katalysatorlag på den bakre siden, og; et andre gassdistribusjonssubstrat på den bakre siden. Det første gassdistribusjonssubstratet har en todimensjonal utstrekning som er mindre enn den ioneledende membranen, mens det andre gassdistribusjonssubstratet har hovedsakelig den samme todimensjonale utstrekningen som den ioneledende membranen ("semi-koekstensiv design"). MEE'ene omfatter også en ikke-støttet fri membranoverflate som gir forbedrede adhesjonsegenskaper av forseglingsmaterialet. Oppfinnelsen vedrører også en fremgangsmåte for fremstilling av MEE-produktene. Dette resulterer i tilveiebringelse av trykkbestandige, gasstette og kostnadseffektive membranelektrodeenheter som kan anvendes i PEM vannelektrolysatorer, regenerative brenselceller eller i andre elektrokjemiske anordninger.
