Title
(DE) BRENNSTOFFZELLENSYSTEM MIT WENIGSTENS EINER BRENNSTOFFZELLE
(EN) FUEL CELL SYSTEM COMPRISING AT LEAST ONE FUEL CELL
(FR) SYSTÈME DE PILE À COMBUSTIBLE COMPORTANT AU MOINS UNE PILE À COMBUSTIBLE
Abstract
(DE)
Ein Brennstoffzellensystem (1) umfasst wenigstens eine Brennstoffzelle (2), die einen Kathodenbereich (3) und einen Anodenbereich (4) aufweist. Das Brennstoffzellensystem (1) weist außerdem eine Austauschvorrichtung (12) auf, welche von einem zum Kathodenbereich (3) strömenden Zuluftstrom einerseits und einem aus dem Kathodenbereich (3) stammenden Abluftstrom andererseits durchströmt ist. In der Austauschvorrichtung (12) wird Wärme vom Zuluftstrom auf den Abluftstrom und gleichzeitig Wasserdampf vom Abluftstrom auf den Zuluftstrom übertragen. Das Brennstoffzellensystem (1) weist außerdem einen Verdichter (6) auf, welcher zumindest unterstützend durch eine Turbine (16) antreibbar ist. Die Turbine (16) ist dabei stromabwärts der Austauschvorrichtung (12) angeordnet und von Abluft durchströmt. Außerdem ist stromaufwärts der Turbine (16) ein katalytisches Material angeordnet, welchem ein brennstoffhaltiges Gas zuführbar ist. Erfindungsgemäß ist das katalytische Material (13) abluftseitig in die Austauschvorrichtung (12) integriert, wobei der Abluftseite der Austauschvorrichtung (12) ein Abgas aus dem Anodenbereich (4) zu zuführbar ist.
(EN)
A fuel cell system (1) comprises at least one fuel cell (2) that has a cathode region (3) and an anode region (4). The fuel cell system further comprises an exchanging device (12), through which an intake air stream flowing to the cathode region (3) and a used air stream discharged from the cathode region (3) flow. In said exchanging device (12), heat is transferred from the intake air stream to the used air stream, and steam is simultaneously transferred from the used air stream to the intake air stream. The fuel cell system also comprises a compressor (6) which can be driven at least in an assisting manner by a turbine (16). Said turbine (16) is disposed downstream of the exchanging device (12) and is penetrated by used air. Furthermore, a catalytic material, to which a fuel-containing gas can be fed, is disposed upstream of the turbine (16). According to the invention, the catalytic material (13) is integrated into the exchanging device (12) at the used air end, to which an exhaust gas from the anode region (4) can be fed.

L'invention concerne un système de pile à combustible (1) comportant au moins une pile à combustible (2) comprenant une partie cathodique (3) et une partie anodique (4). Le système de pile à combustible (1) comporte également un dispositif d'échange (12) qui est parcouru, d'une part, par un flux d'air entrant s'écoulant vers la partie cathodique (3) et, d'autre part, par un flux d'air sortant provenant de la partie cathodique (3). Dans le dispositif d'échange (12), la chaleur est transférée du flux d'air entrant au flux d'air sortant, la vapeur d'eau étant simultanément transférée du flux d'air sortant au flux d'air entrant. Le système de pile à combustible (1) comporte en outre un compresseur (6) pouvant être entraîné par une turbine (16) au moins de manière assistée. La turbine (16) est placée en aval du dispositif d'échange (12) et parcourue par l'air sortant. De plus, un matériau catalytique, auquel peut être amené un gaz contenant un combustible, est placé en amont de la turbine (16). Selon l'invention, le matériau catalytique (13) est intégré dans le dispositif d'échange (12) côté air sortant, un gaz sortant de la partie anodique (4) pouvant être amené au dispositif d'échange (12) côté air sortant.
