Definitions
- the present invention relates to a power supply module that can provide electric power from fuel cells, and to a power cabinet in which one or more power supply modules are installed.
- Fuel cell stacks ie arrangements of several fuel cells of the same type to increase the voltage or the maximum current to be delivered, are not functioning alone as a power supply module. Fuel cells need more peripheral components and elements, so that the necessary supply media such as hydrogen and air, possibly also cooling water, can be made available to a sufficient extent, while often energy supply modules with fuel cells are additionally equipped with DC / DC converters, because the fuel cell stack a span large voltage swing depending on the current drawn.
- FCS 09015 WO 14.04.2009 Therefore, a mounting system is to be provided so that individual power supply modules are interchangeable, while the remaining power supply modules are still operable.
- FIG. 5 shows both a
- US 2003/0035985 Al different air duct concepts can be removed through a cabinet-like housing.
- US 2003/0035985 Al focuses on the construction of a power cabinet with zinc-air batteries and only marginally touches the aspect of hydrogen-powered primary electrolyte membrane fuel cells.
- fuel cell and fuel cell stack are used interchangeably in cases in which it is irrelevant whether a single or several cells are operated together.
- a gas-powered power supply module interchangeably designed so that a cabinet with at least one corresponding power supply module is particularly simple and easy to build. For service and maintenance, an easy and fast assembly and disassembly of the power supply module in the cabinet is to be made possible.
- the term cabinet means any kind of holder, frame or housing in which a power supply module according to the invention can be mounted or arranged.
- the term front means the entire area of the power supply module, which can be reached by a person or an operator while in front of the front of the power supply module or a cabinet or a corresponding rack with his hands. It is particularly easy
- FCS 09015 WO 14.04.2009 replace a power supply module according to the invention, when the power transmission mechanism from the front, so the front side, is releasable.
- the power supply module has at least one fuel cell stack with at least one fuel cell, preferably a fuel cell stack with polymer electrolyte membrane fuel cells (PEM-Bz).
- PEM-Bz polymer electrolyte membrane fuel cells
- Polymer electrolyte membrane fuel cells which have a dry electrolyte can very effectively convert electrical energy from hydrogen and oxygen, which can be taken from the air, for example.
- hydrogen can be introduced directly and directly or by a hydrogen carrier, for example in the form of a hydrocarbon compound.
- the power module is designed to be mounted in a frame.
- the frame or cabinet has a side where all interfaces such as hydrogen pipes with valves and couplings, ventilation ducts and electrical connectors run.
- the side along which the hydrogen distribution pipe is routed is called the rear side.
- To connect the power supply module to the hydrogen distribution line a gas quick coupling is provided.
- the quick throttle can be released again.
- To release a power transmission mechanism is provided.
- the power transmission mechanism is to be triggered from a side other than the rear side, so to speak, from another side.
- the power transmission mechanism with which the quick throttle coupling can be released may be, for example, an operating mechanism or a fixing means.
- the fixing in this case fulfills a dual function, on the one hand with him the gas quick release is releasable and on the other it performs fixing function, in particular by the fuel cell module can be mounted in the frame so.
- the actuation mechanism may include, for example, an engagement means such as a lever, knob, a specially designed tool, or a handle. Further, it may comprise a traction system or a sliding system, via which the gas quick coupling operated, in particular solved, can be.

- the engagement means is out of the front panel or is separated from the front panel.
- the engagement means may be, for example, a release handle.
- the engagement means may be, for example, a screw-in release handle. If a special screw thread is used for the screw connection, not every screw attachment can be used, so that only
- FCS 09015 WO 14.04.2009 Persons in possession of the correct means of engagement can trigger the actuating mechanism after screwing on a release handle. But once the operating mechanism has been made operable, it can be easily operated, inter alia, due to its arrangement. Thus, on the one hand, unauthorized triggering is avoided, while by authorized persons, the actuating mechanism can easily be triggered. At the same time, damage to the engaging means is prevented.
- a screw-in release handle and a specially designed tool for example, a specially shaped Allen key or hexagon, a wrench or a hook, a lever, a tab, a knob, a slider or other handle provide.
- a further alternative embodiment provides that the power transmission mechanism is a fixing means.
- the front panel is thereby bolted directly to the mounting frame. By loosening the screws, the gas quick release is released.
- the fixative has a dual function here: fixing the module and triggering the quick release gas coupling.
- the gas quick coupling has a protruding, engaging in the other part part, which can be described as a male part.
- the female part can be called a female part. It is favorable if the male part is mounted in the gas distribution pipe, while the female part of the gas quick coupling belongs to the energy supply module. He is part of the power supply module.
- the connection from the operating mechanism to the quick-release gas coupling can be made possible by means of a pulling system.
- the train system can be guided by rollers. By means of rollers, for example, a deflection can be made possible.

- Turning mechanism triggers In the normally-off position, the rotation mechanism can exert a closing force on the high-speed hydrogen clutch. Should the closing force on the
- Gas quick release be solved, for example by the operation, in particular pulling, pressing or turning, or moving the mechanism as a sleeve, so will from the self-locking
- the uncoupled position is preferably free of force or with as little force as possible.
- the pushing movement of the power supply module in the frame can be used simultaneously to overcome the necessary closing force, while for fast decoupling only a minimum release force is necessary, namely to trigger the rotary, pulling or sliding mechanism and to overcome the Einfahrrange of the male part of the gas quick coupling in the female part of the quick release gas coupling.
- a spring can be used for power support.
- the module has handles.
- the engagement means may be part of these handles.
- the Eingriffsmittei be arranged so low that the handles not disturbing, but protectively accompany the intervention neighbor or are arranged neighborly to this.

- the hydrogen-carrying side of the gas quick coupling is safe to close.
- the gas quick coupling has a self-closing side.
- the second side can also be self-closing.
- the quick gas coupling has sealing rings. The easily diffusing gas, such as hydrogen, is safely held in the engaged high-speed gas coupling. If the gas quick coupling is an almost rotationally symmetrical component, in particular a tubular component, then the coupling and uncoupling process is particularly simple.
- the pulling system can be equipped with a spring.
- the spring can cause by their bias a preferred position of the tension system.
- the preferred position is the closed holding position. Only when the spring force has been overcome, the train system and thus the throttle quick coupling can be changed or adjusted in a disconnected position.
- actuation points can be present on the quick-release gas coupling. So that synchronous, simultaneous and coordinated can be done the engagement and disengagement of the gas quick coupling, the different points should be operated simultaneously.
- a simultaneity can be made possible by a double rope system, a Y-Zugseilsystem or by a centrally-controlled pull rope as a release rope.
- FCS 09015 WO 14.04.2009 The energy supply module has in an advantageous embodiment only of such a size that not the complete cabinet is filled. Thus, an air duct remains between the cabinet inner wall and power supply module. If a lower, near-ground side is selected as the connection point, then escaping gases can easily be diluted, in particular in the case of rear ventilation, by means of an air stream present in the energy supply module.

- the train system is advantageously a cable system.
- the female side of the quick release gasket is stationarily arranged near the ground in the region of the rear side of the energy supply module for an incoming side of the quick release gasket, so that the part of the quick disconnect gas inlet entering the energy supply module is a first connection component from the bottom.
- the quick throttle is fixable via the power transmission mechanism.
- the flow-through deconcentration chamber of the electricity cabinet is ventilated by external ventilation.
- the flow-through deconcentration chamber surrounds the mounting frame.
- At least part of the hydrogen quick coupling is disposed in an exhaust duct.
