Abstract

I en fullstendig innvendig manifoldforsynt brenselcelle- stabel er hver separatorplate (40) og elektrolytt (20) forsynt med et antall innbyrdes fluktende perforeringer (24, 25, 47, 47', 48, 48') som danner gassmanifolder som strekker seg i cellestabelens lengde. Hver perforering gjennom separator- platen omsluttes av en utflatet manifoldvåttetningsstruktur (43, 45, 46) som strekker seg til kontakt med elektrolyttene på hver side av separatorflåten, og derved danner separator- plate (elektrolyttvåttetninger) når cellene er i drift. Kanalene gjennom den forlengede manifoldvåttetningsstruktur danner gassforbindelse mellom et manifoldsett og anodekamrene på en side av separatorplatene, kanalene gjennom den forlenge- de manifoldvåttetningsstruktur på den motsatte side av separa- torplatene danner gassforbindelse mellom et andre manifoldsett og katodekamrene på den annen side av separatorplatene, og kanaler gjennom den forlengede manifoldtetningsstruktur ved en reaktantgassmanifold danner forbindelse med innbyrdes adskilte omformerkamre. Forlengede våttetningsstrukturer av tynnplate- metall gir begrenset fleksibilitet og elastisitet som sikrer tilfredsstillende avtetning. Denne konstruksjon muliggjør fullstendig innvendig manifoldstyring av samt adskilling av brensel- og oksidantgasser til hver av brenselcelleenhetene i brenselcellestabelen, mens reaktantgass overføres til omform- erkamrene som er anordnet med innbyrdes avstand langs celle- aksen, for å omforme hydrokarbonholdig gass og levere hydro- genanriket gass til brenseltilførselsmanifolden.
