Abstract

Die Erfindung betrifft eine Vorrichtung zur Bestimmung der Stromdichteverteilung in einer Brennstoffzelle oder einem Brennstoffzellenstapel, umfassend wenigstens eine Brennstoffzelle mit zwei bipolaren Platten, einer Membran-Elektroden-Einheit sowie einer Endplatte. Die Vorrichtung ist DOLLAR A gekennzeichnet durch wenigstens eine segmentierte, leitfähige Platte, die zwischen einer bipolaren Platte und einer Endplatte angeordnet ist, wobei jedes Segment dieser Platte über zwei Drähte über Kontaktpunkte elektrisch kontaktiert ist. DOLLAR A Im Gegensatz zum bekannten Stand der Technik, bei dem zur Ermittlung der Stromdichteverteilung häufig einzelne Elektroden oder Flow-fields segmentiert wurden, bleibt bei der erfindungsgemäßen Vorrichtung die eigentlich zu untersuchende Brennstoffzelle unverändert. Die zusätzlich eingebrachte segmentierte Platte und ggf. weitere Platten können nach der Ermittlung der Stromdichteverteilung für diese Brennstoffzelle einfach wieder ausgebaut werden.The invention relates to a device for determining the current density distribution in a fuel cell or a fuel cell stack, comprising at least one fuel cell with two bipolar plates, a membrane electrode assembly and an end plate. The device is DOLLAR A characterized by at least one segmented conductive plate disposed between a bipolar plate and an end plate, each segment of that plate being electrically contacted via two wires via contact points. DOLLAR A In contrast to the known state of the art, in which individual electrodes or flow fields were often segmented to determine the current density distribution, the actual fuel cell to be investigated remains unchanged in the device according to the invention. The additionally introduced segmented plate and possibly other plates can be easily removed after determining the current density distribution for this fuel cell.
