摘要： A method for producing a multi-layer bipolar plate for an electrochemical device is disclosed. The method includes producing at least one sealing element made of an elastic material on a first bipolar plate layer of the bipolar plate; connecting the first bipolar plate layer with the sealing element produced thereon and a second bipolar plate layer of the bipolar plate by welding along at least one connection welding seam, in which method an impairment to the sealing element produced on the first bipolar plate layer as a result of a subsequent welding operation can be reliably avoided and the freedom of design of the electrochemical unit is preferably increased, and that during the welding operation, the second bipolar plate layer faces toward a welding energy source and that during the welding operation, a weld pool produced by the welding energy source does not completely penetrate the first bipolar plate layer.

摘要： A method of manufacturing electrochemical cell stacks of different sizes or configurations is disclosed in which a first planar module having a first planar size and configuration is assembled from a first inventory of parts including planar modular parts having mating surfaces along connectable ends. The planar modular parts are connected in a co-planar configuration to form the first planar module having the first size and configuration. A second inventory of parts including planar modular parts in common with the first inventory is identified, and a second planar module having a different planar size or configuration than the first planar module is assembled from the second inventory. The first and second planar modules are assembled with other planar modules and component to form electrochemical stacks corresponding to the planar size and configuration of the respective first or second planar module.

摘要： Composite members, a fuel cell and manufacturing method, where the composite members are mounted on a base and comprise a first insulator and a second insulator layered on either side of an interconnector, exposed in a chamfered portion on opposite corners. Between a pair of the composite members is formed an electrolyte film. An anode is formed so as to cover the anode surface of the electrolyte film and an anode-side protrusion. The anode formed at the top of anode-side protrusion is stripped, forming a flat exposed surface on the top of the anode-side protrusion. A cathode is formed so as to cover the cathode surface of the electrolyte film and a cathode-side protrusion. The cathode formed on the top of the cathode-side protrusion is stripped using a spatula, a blade, etc., forming a flat exposed surface on the top of the cathode-side protrusion.

摘要： A metal-supported, planar cell arrangement (200) comprising at least one pair of cells (110a, 110b), each cell (110a, 110b) comprising a metal substrate (120a, 120b) having first and second sides and a porous region (124) providing fluid communication between the sides, planar cell chemistry layers (111, 112, 113) comprising fuel electrode, electrolyte, and air electrode layers being coated or deposited over, and supported by, the porous region (124) on the first side, wherein the metal substrates (120) are in a stacked arrangement with their cell chemistry layers (111, 112, 113) overlying each other such that either both their first sides, or, both their second sides face inwardly in a spaced, opposed relationship, the inwardly facing sides thereby defining a common first fluid volume (140) between them for one of fuel or oxidant.

摘要： In order to prevent a reduction in workability when inserting an insulator, the insulator is to be disposed between a stacked body having a cell stack including a plurality of stacked unit cells and an end member to be disposed outward from the cell stack in stacking directions of the plurality of unit cells, and a covering to be disposed so as to separate in a perpendicular direction to the stacking directions from a side face of the stacked body parallel to the stacking directions. In a state where an end portion of the end member in the perpendicular direction is closer to the covering than an end portion of the cell stack in the perpendicular direction, and the insulator is disposed between the stacked body and the covering, the insulator includes a planar portion for covering at least a part of the side face, and a protruded portion disposed in the planar portion and protruded toward one or more unit cells near the end member among the plurality of unit cells constituting the cell stack.
