an engine auxiliary system including a hydrogen system, an air system, and a water thermal management system, the engine auxiliary system integrated below and mounted directly on the stack module.

The fuel cell integrated system according to the present application solves the problem of high integration of large volume hydrogen fuel cell systems in full vehicle applications. All bop parts (galvanic pile auxiliary system) of the fuel cell engine are directly integrated under the galvanic pile, which is beneficial to improving the integration level of the engine, and no parts are arranged above and around the galvanic pile, thus being beneficial to reducing the weight of the galvanic pile shell and being beneficial to maintaining and overhauling the galvanic pile. And the components needing repair and maintenance in bop are placed on the exposed side through reasonable arrangement, so that bop can be maintained and repaired easily.

Specifically, as shown in fig. 1 to 6, the fuel cell integrated system includes a stack module 10 and an engine auxiliary system 20. The stack module 10 is integrated with an electric control system and a data acquisition system. The engine auxiliary system 20 includes a hydrogen system, an air system, and a water heat management system. The engine auxiliary systems 20 (hydrogen system, air system, water heat management system, etc.) are integrated below the stack module 10 and are mounted directly on the stack module 10. Since the components of the engine auxiliary system 20 are directly mounted on the stack module 10, it is not necessary to fix the components of the engine auxiliary system 20 to the peripheral frame, so that the peripheral frame can be omitted, a higher integration level can be achieved, and the weight of the engine can be reduced.

Specifically, in the present application, the integrated design may be based on the bottom plate 13 and the end plate 14 of the stack module 10. Specifically, the bottom plate 13 and the end plate 14 of the stack module 10 may be used as bearing surfaces (fixing surfaces) of the entire engine auxiliary system. In one embodiment, the hydrogen system, air system, and water thermal management system are secured to the bottom plate 13 and end plate 14 of the stack module.

In one embodiment, the engine auxiliary system 20 further includes a wiring harness 30.

The wire harness 30 may also be secured to the bottom plate 13 and the end plate 14 of the stack module 10.

In one embodiment, the fuel cell integrated system further includes a removable engine mount 40. Because the engine support 40 is detachable, can be directly fixed mounting on large and medium-sized passenger cars, other motorcycle types such as compatible commodity circulation car simultaneously.

As shown in fig. 4 and 5, the left side of the stack module 10 is the engine high voltage output 11, and the right side of the stack module 10 is provided with the stack manifold 12. The engine high pressure output 11 is output to the vehicle. The stack manifold 12 includes a cooling water inlet, a cooling water outlet, an air inlet, and a hydrogen inlet.

An exemplary embodiment of the engine assist system 20 is described in detail below with reference to FIG. 6.

In the air system, the air inlet piping is connected to the stack manifold 12, specifically, to the air inlet 121 of the stack module 10. A humidifier, a throttle valve, an intercooler, and an air bypass valve are integrated in this order below the stack module 10. A humidifier and an engine exhaust outlet are connected below the air exhaust outlet 122 of the stack module 10 in sequence.

In one embodiment, the engine may be equipped with more than one type of air compressor, and the air compressor and its controller are not mounted on the engine, but are mounted separately on the vehicle. The engine is connected with an air compressor which is independently arranged on the whole vehicle through a pipeline.

In one embodiment, the hydrothermal management system (cooling system) is connected to the stack manifold 12, specifically, to the coolant inlet 123 and the coolant outlet 124 of the stack module 10, and integrates a thermostat, a PTC heater, and a water pump in sequence below the stack module 10.

In an exemplary embodiment according to the present application, there is also provided a vehicle having the fuel cell integrated system described above.

In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., are generally based on the orientation or positional relationship shown in the drawings, and are used for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element being referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of protection of the present application is not to be construed as being limited.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
