- inter-card links notably leads to a reduction of parasitic electromagnetic emissions and makes it possible to eliminate inter-card operation dependencies.
- the reliability of the control electronics and power of the device is thus improved.
- a gain in mass is also obtained via a reduction in the number of inputs / outputs previously related to inter-card links.
- the air sucked by the device travels inside the channels along the housing formed by the assembly of the housing parts, thereby ensuring the cooling of the electronic components of the device, the heat emitted by the latter being evacuated via the air flow through the channels.
- the housing parts can be fixed together by means of flanges, two corresponding flanges defining between them a cavity in communication with the housing housing, a portion of the electronic card being housed in said cavity.
- the assembly of two respective flanges on either side of each part of the housing allows to provide an additional volume for the insertion of the electronic card between the housing parts.
- the housing may be aluminum.
- the electromechanical device may be an air compressor or a fan.
- the invention also proposes, in another aspect, a fuel cell system comprising a fuel cell and an air compressor for supplying air to the fuel cell, the air compressor constituting the generation system. of air summarized above.

In other non-illustrated examples, other means can be envisaged to ensure the attachment of the first end 201 to the opening 101, for example a bonding or welding of the housing 200 with the electromechanical device 100.
- the housing 200 is formed of two parts 210, 220 which, when assembled, define a closed housing 204 intended to house the electronic card 300.
- each part 210, 220 forming the casing 200 is made of aluminum, other materials that can be envisaged.
- Each portion 210, 220 comprises a hollow wall defining a channel 211, 221 extending between the two ends 201, 202 of the housing 200. At the first end 201, each channel 211, 221 opens out opposite the opening 101 air intake of the electromechanical device 100.
- the electromechanical device 100 is supplied with air by air conveyed by the channels 211, 221.
- the parts 210, 220 can be seen as lower and upper covers of the housing 1, each of these hoods with a vein of air defined by the Channels 211, 221. The exit of these air veins leads to the air intake opening 101 of the electromechanical device 100.
- Each channel 211, 221 being formed in a portion 210, 220 separate from the housing 200, these channels are fluidly isolated from each other, and the housing 204.
- the channels 211, 221 extend in the same direction along the axis X along the housing 204 when the parts 210, 220 are assembled.
- the housing 204 for the electronic card 300 formed by the assembly of the first portion 210 and the second portion 220, is isolated from the air flow A through the channels 211, 221, Bypassing the housing 204.

- a portion of the electronic card 300 is then housed in each of the cavities 205, 206.
- the electronic card 300 can be maintained in the housing 204 and the cavities 205, 206 by various fixing means.
- the assembly of the flanges 212, 222 makes it possible to form grooves 232 extending radially towards the inside of the casing 200, thus making it possible to maintain the electronic card 300.
- the electronic card 300 can be attached to one of the parts 210, 220 via a screw / nut system.
- the shape of the parts 210, 220 can be adapted to the shape of the electromechanical device 100.
- the electromechanical device 100 has a substantially cylindrical shape along the X axis and its opening 101 of air intake a circular shape. Consequently, the parts 210, 220 of the housing 200 are made in the form of two half-cylinders.
- the housing 200 extends in the example shown in the extension of the opening 101.
- the channels 211, 221 then have a C-shaped section.

The electronic card 300 is housed in the housing 200. Advantageously, the insertion of the electronic card 300 between the two parts 210, 220 of the housing 200 allows for at least one electrical connection 301 in direct communication with the electromechanical device 100. The electronic card 300 can thus be electrically connected to the electromechanical device 100 without passing through the first channel 211 or the second channel 221, and has no impact therefore not the air supply of the electromechanical device 100. Thus, in order to ensure the electrical connection of the device 100 electromechanical with the electronic control and / or power components of the electronic card 300, no air flow vein undergoes performance degradation due to the presence of electrical connection elements passing therethrough.
- the use of a single electronic card 300 disposed in the housing 204 also makes it possible to reduce the number of electrical connections compared to existing solutions, in particular avoiding any inter-card connections. We thus obtaining a gain in volume and mass of the electronics for the electromechanical device 100, as well as a reduction in the electromagnetic radiation emitted by the various electronic components.
- the structure of the proposed housing 200 furthermore makes it possible to ensure efficient cooling of all the electronic components of the electronic card 300.
- a stream of air A is sucked into the inlet of the casing 200, that is, say at the second end 202, it enters the channels 211, 221 and is conveyed by them.
- the air then flows through the channels 211, 221 along the housing 204, the channels being separated from the housing 204 by a portion of the parts 210, 220, allowing by thermal conduction the dissipation of the heat emitted by the components of the card 300 electronic.
