Abstract:
Bei einem Brennstoffzellenmodul (1) umfassend eine Brennstoffzelleneinheit (2) und eine Betriebsmittel-Versorgungseinheit (3) zur Versorgung der Brennstoffzelleneinheit (2) mit Betriebsmitteln, wobei die Brennstoffzelleneinheit (2) zumindest einen Stapel (5) von Brennstoffzellen (5'), vorzugsweise einen kaskadierten Stapel (5) von Brennstoffzellen (5'), aufweist, wobei die Betriebsmittel-Versorgungseinheit (3) Stromanschlüsse (10) zum Abgreifen eines in den Brennstoffzellen (5') erzeugten Stromes von außerhalb des Brennstoffzellenmoduls (2) und Betriebsmittelanschlüsse (13) zur Zu- und Abfuhr von Betriebsmitteln zu bzw. von dem Brennstoffzellenmodul (1) aufweist, wobei die Brennstoffzelleneinheit (2) und die Betriebsmittel-Versorgungseinheit (3) über eine zwischen den beiden Einheiten (2, 3) angeordnete Verbindungs-Platte (4) miteinander verbunden sind, wird die Verfügbarkeit erfindungsgemäß dadurch weiter verbessert, dass die Verbindungs-Platte (4) eine erste Teilplatte (4a) und eine zweite Teilplatte (4b) umfasst, die voneinander lösbar sind, um die Brennstoffzelleneinheit (2) von der Betriebsmittel-Versorgungseinheit (3) zu trennen.
Abstract:
A fuel cell system includes at least one modular enclosure having a top wall, a bottom wall, and a plurality of side walls that connect the top wall and the bottom wall and close off the modular enclosure on all sides; at least one fuel cell stack disposed within the at least one modular enclosure; at least one piping manifold configured to supply at least one process gas to the at least one fuel cell stack and to receive at least one exhaust process gas from the at least one fuel cell stack; and at least one process gas seal configured to seal the at least one piping manifold. The at least one process gas seal is effected via a static force from a weight of the at least one fuel cell stack or a weight of the at least one piping manifold.
Abstract:

Abstract:
Systems and methods are provided for arranging processing units in a common volume to allow for processing of a fluid flow as part of a mass and/or heat transfer process. Fuel cells are examples of processing units that include separate flow paths for processing two input fluid flows with mass and/or heat transfer between the separate flow paths. The arrangements described herein can allow a gas phase fluid flow to be delivered to a first process flow path of processing units in a common volume. The gas phase fluid flow can be delivered in a relatively uniform manner without the use of an intervening manifold to distribute gas from the common volume into the processing units.
Abstract:
A glow plug and method of forming the same, the glow plug including a housing, a heating element extending from a first end of the housing, and a sealing element attached to the heating element and the first end of the housing. The sealing element may include an annular base and a tubular collar extending from the base. The sealing element may be attached using an ABA gold braze. The sealing element may include an austenitic nickel-chromium alloy. The glow plug may further include a landing pad configured to attach a lead wire to the heating element. The landing pad may include a collar and a lead connection extending from the collar and may be attached using the ABA gold braze. The glow plug may further include a glass sealing ring disposed between the heating element and the housing. The sealing ring may be attached using the ABA gold braze.
