Abstract

Przedmiotem zgłoszenia jest uszczelnienie hybrydowe stosów dwustronnych stałotlenkowych ogniw paliwowych, które charakteryzuje się tym, że składa się z: uszczelek zewnętrznych (1, 3) umieszczonych na wyprowadzeniach prądowych strony anodowej (6) ogniw DFC (8) i okalających uszczelki wewnętrzne (2), przy czym każda uszczelka zewnętrzna (1), ogniwa DFC (8), posiada na swej powierzchni dwa podłużne otwory (5) przechodzące na wylot przez powierzchnię uszczelki zewnętrznej (1), uszczelek wewnętrznych (2), umieszczonych wokół kolektorów gazowych wlotowych (9) i wylotowych (10), mających postać kanałów, dla kolejnych ogniw DFC (8) w stosie, przy czym uszczelki wewnętrzne (2) cechują się mniejszą podatnością na odkształcenia w porównaniu do uszczelek zewnętrznych (1), a także z zintegrowanych konektorów prądowych, w postaci taśm metalowych (4), przy czym taśmy metalowe (4) są przełożone przez otwory (5) w wybranych uszczelkach zewnętrznych i wyprofilowane równolegle do powierzchni uszczelki zewnętrznej (1) po stronie wyprowadzenia prądowego strony anodowej (6) ogniw DFC (8), natomiast po stronie wyprowadzenia prądowego strony katodowej (7) ogniw DFC (8) taśmy są wyprofilowane równolegle do powierzchni ogniwa DFC (8) oraz łączą wyprowadzenia prądowe strony katodowej (7) pomiędzy dwoma stronami czynnymi ogniwa DFC (8).The subject of the application is a hybrid sealing of double-sided stacks of solid oxide fuel cells, which is characterized in that it consists of: external seals (1, 3) placed on the current leads of the anode side (6) of DFC cells (8) and surrounding internal seals (2), wherein each external seal (1) of DFC cells (8) has on its surface two elongated holes (5) passing through the surface of the external seal (1), internal seals (2), placed around the inlet (9) and outlet (10) gas collectors, in the form of channels, for subsequent DFC cells (8) in the stack, wherein the internal seals (2) are characterized by lower susceptibility to deformation in comparison to the external seals (1), and also integrated current connectors in the form of metal strips (4), wherein the metal strips (4) are inserted through the holes (5) in selected external seals and profiled parallel to the surface of the external seal (1) on the current output side of the anode side (6) of the DFC cells (8), while on the current output side of the cathode side (7) of the DFC cells (8), the tapes are profiled parallel to the surface of the DFC cell (8) and connect the current outputs of the cathode side (7) between the two active sides of the DFC cell (8).
