Definitions
- Connection structure for connection of a section of fluid circuit to a chamber, and fuel cell cell comprising the same.
- the present invention relates to connection structures between a section of fluid circuit and a chamber delimited on at least one side by a thin metal sheet provided with at least one orifice for access to the chamber.
- Connecting a tube to a thin sheet presents many difficulties, both in terms of mechanical strength and sealing, in particular with sheets which are difficult to weld such as alloy steels. The difficulties are even greater when the chamber has a very small useful interior volume. The problems are further increased depending on the fluids concerned, aggressive or oxidizing, as is the case in particular in fuel cell cells.
- the object of the present invention is to provide a simple, compact and reliable connection structure, including with very thin sheets, less than 0.4 mm and with very small chamber volumes.
- connection structure comprises a metallic tubular element having a first end crimped in the orifice of the sheet and a second end connectable to the section of the circuit typically via a connection member, advantageously made of plastic material. , comprising a channel receiving at least the second end of the tubular element and secured in sealed manner to the latter.
- connection member comprises an internal chamber connectable to the section of the circuit.
- the present invention also relates to a fuel cell cell where the sheet metal forms, by stamping, a series of parallel channels and is joined in leaktight manner to a proton exchange membrane.
- FIG. 1 is a schematic perspective view of a fuel cell half-cell showing the configuration of the stamped shaped sheet
- FIG. 2 is a diagrammatic view in enlarged section of a connection structure according to the invention.
- FIG. 3 is a top view of two adjacent fuel cell cells provided with connection structures according to the invention.
- the sheet 4 typically made of stainless steel, has a thickness less than 0.5 mm, typically less than 0.4 mm.
- Channels 6 have a height (wave amplitude) less than 5 mm, typically less than 2 mm.
- the lateral channels of the sheet 4 are each provided, at one of their ends, with an access orifice 7 for connection to a section 8 of the fluid circuit, typically hydrogen on the one hand and a gaseous mixture. containing oxygen on the other hand in the case of fuel cells.
- connection structure for the connection of the fluid circuit section 8 to the orifice 7 of the sheet 4, comprises a metallic tubular element 9, typically also made of steel stainless steel, overall diameter slightly greater than that of the orifice 7 and comprising a thinned end 10 of small axial extension (of the order of twice the thickness of the sheet 4) and substantially the same diameter as that of the orifice 7 to be introduced into the latter with the rear shoulder 11 coming to bear against the outer surface of the sheet 4.
- the projecting end of the thinned end 10 of thickness between 0.05 and 0 , 5 mm, preferably between 0.1 and 0.3 mm, is crimped in a sealed manner in the hole 7, thus securely joining the tubular element 9 to the sheet 4.
- connection structure further comprises a connection member 12, advantageously of molded polymer material, of generally elongated configuration, defining an internal tubular chamber 13 having a main direction opening at one end through a connection port of enlarged diameter 14 and, at the other end, with a channel 15 extending orthogonally to the chamber.
- the inside diameter of the channel 15 is slightly greater than the outside diameter of the tubular element 9 and the latter is force-fitted into the channel 15 with the application of ultrasound which causes total fusion or partial of the edges of the channel, thus sealingly joining the tubular element 9 to the connection member 12, the outer face of which, in which the channel 15 opens, bears on the outer face of the sheet 4.
- the chamber 13 In configuration assembled, the chamber 13 extends parallel to the sheet 4, beyond the latter, thus allowing easy connection of the connection orifice to the section of fluid 8.
- the connecting member 12 further comprises a pin 16 parallel to the channel 15 and which is positioned in a hole 17 formed in the plane peripheral zone of the sheet 4, the pin being deformed when hot or by bolting to consolidate the positioning and maintenance of the member 12 relative to the sheet 4.
- connection orifice 14 may be of a shape and dimension adapted to allow any type of sealed connection, advantageously removable, to one end of tubing such as the circuit section 8.
