Definitions
- the present invention relates to a periphery formed as a self-contained unit for a fuel cell unit, for example a fuel cell stack.
- a fuel cell-based energy supply system comprises, in addition to at least one fuel cell, means for supplying, controlling and conditioning the at least one fuel cell.
- the entirety of these devices will be referred to as peripherals.
- the periphery comprises the following components: means for supplying the reaction media, ie at the anodes of the fuel cell electrochemically oxidizable fuels (for example hydrogen or methanol) and the cathodes of the fuel cell electrochemically reducible oxidizing agents (typically air or oxygen), means for process control and optional Facilities for cooling.
- Fuel cell-based power supply systems for practical applications typically include a plurality of fuel cells that are electrically connected in series.
- the fuel cells are arranged in the form of a stack, this type of construction being referred to as a fuel cell block, fuel cell stack or fuel cell stack.
- the fuel cell stack is usually integrated into the periphery so that fuel cell stacks and peripherals form a functional and spatial unit.
- fuel cell stacks and peripherals are directly matched with regard to dimensioning, performance, function and intended use. Therefore, it is generally not possible to simply extract the fuel cell stack from such a fully integrated system and replace it with another fuel cell stack not specifically configured for that system without making significant changes to the design and sizing of the peripherals.
- German Patent Application DE 10 2004 059 776 A1 discloses a modular fuel cell system.
- This comprises a fuel cell device with one or more fuel cell blocks, an oxidizer supply device, a fuel supply device and a control device.
- the fuel cell device and / or the Oxidator- supply device and / or the fuel supply device and optionally the cooling device and the control device are designed as separate modules, wherein in a module, the functional components of the respective device are arranged (for example in a housing), the corresponding module forms a unit which is positionable as a whole, and the corresponding module has a communication interface with terminals.
- each module can be optimized, adjusted, positioned and replaced or repaired if necessary.
- the completely modular structure results in the periphery breaking down into a plurality of individual systems, each representing separate components.
- the fuel cell system comprises a total of a plurality of separate components, each to handle, to position, connect to each other according to their respective functions and possibly also to be transported. This is a disadvantage especially in non-fixed applications. Another disadvantage is in comparison to a completely integrated system of fuel cell stack and periphery inevitably increased space requirements.
- the invention therefore proposes a fuel cell system in which a fuel cell unit comprising at least one fuel cell on the one hand and the associated peripherals on the other hand are arranged spatially separated from each other, wherein the components of the periphery are housed together in a self-contained unit.
- the periphery forms an independent device with an independent function, ie a device for starting up or operating fuel cell units.
- the peripheral according to the invention which is provided for combination with a fuel cell unit comprising at least one fuel cell, comprises the following components:
- a device for supplying the fuel cell unit with fuel - means for supplying the fuel cell unit with
- the components of the peripheral module are on a common platform, for example in a housing, a box o.a. housed so that they form an independent, self-contained unit.
- a fuel cell system comprises a fuel cell unit comprising at least one fuel cell and a periphery spatially separated from the fuel cell unit comprising the following components:
- a device for supplying the fuel cell unit with fuel a device for supplying the fuel cell unit with oxidizing agent, - a measuring, control, regulating and operating device and optionally a device for cooling the fuel cell unit, - A -
- the fuel cell unit of the fuel cell system according to the invention includes a plurality of fuel cells, which are advantageously arranged in a fuel cell stack.
- they are polymer electrolyte membrane fuel cells (PEMFC).
- the fuel for example, hydrogen or methanol (for example, in the form of a methanol-water mixture) is used.
- Hydrogen is provided by means of a suitable memory, for example a metal hydride storage or a compressed gas cylinder, wherein the memory for the operation of the fuel cell unit is fluidly connected to the periphery according to the invention.
- Oxidizing agent usually oxygen or air is used. This is sucked from the periphery of the ambient air. In the periphery of a corresponding device is provided.
- the peripheral according to the invention has connections in order to produce fluidic connections for the transport of the reaction media, ie the fuel and the oxidizing agent to the fuel cell unit.
- the periphery comprises a device for cooling the fuel cell unit, connections for fluidic connections for the supply and removal of the coolant to the fuel cell unit are to be provided.
- the coolant used is water, optionally with antifreeze additive, or another common coolant.
- air cooling can also be used.
- a liquid coolant the delivery of the coolant is accomplished by a pump provided in the periphery.
- the periphery has a fan for the air used as coolant.
- peripheral according to the invention is to be used exclusively in combination with passively cooled fuel cell units, it is not necessary to provide a device for cooling the fuel cell unit in the periphery.
- the peripheral according to the invention has an electrical connection in order to produce an electrical connection to the fuel cell unit and to remove electrical power from the fuel cell unit. It also has an electrical connection for at least one consumer, which receives the electrical power taken from the fuel cell unit.
- the electrical and fluidic connections between fuel cell unit and periphery are prepared in a known manner.
- certain operating variables such as the temperature and voltage of the fuel cell unit, the function of the cooling circuit, the temperature of the incoming and outgoing coolant, the inlet air pressure and the hydrogen pressure can be controlled and monitored.
- a measuring, control, regulating and operating unit can be used, so that a regulation of certain operating variables is possible.
- sensors For the quantities to be measured, appropriate sensors must be provided in the periphery or in the fuel cell unit, as well as the necessary signaling connections for signal transmission to the measuring, control, control and operating unit.
- the peripheral according to the invention also has an input for the supply of electrical auxiliary energy.
- the energy requirement of the components of the periphery requiring electrical energy air compressor, coolant pump, etc.
- the electrical energy can be taken from the power grid or another power source, such as a battery.
- the decoupling of the power of the fuel cell stack from the electrical power requirement of the periphery makes it possible to independently evaluate the performance of the fuel cell stack.
- the need for auxiliary power to be kept as small as possible it is also possible to meet the power requirements of the periphery directly from the power output of the fuel cell unit.
- the periphery is then switched electrically as a consumer.
- the system according to the invention is distinguished from the prior art by a multiplicity of advantages. Compared to the completely modular system according to DE 10 2004 059 776 A1, the construction which is considerably more compact due to the integration of the peripheral components in a structural unit should be emphasized, which facilitates handling and transport.
- the peripheral according to the invention enables a simple and safe startup of fuel cell units. This is particularly advantageous for non-fixed applications and limited space.
- the fuel cell unit is not rigidly connected to the periphery and therefore can be replaced. It can therefore be connected without significant conversion effort different fuel cell units, put into operation and examined.
- the periphery formed according to the invention as a self-contained unit allows a high flexibility in testing and evaluating fuel cell units, in particular also different fuel cell units, e.g. Fuel cell stacks, compared to each other.
- fuel cell stacks e.g. Fuel cell stacks
- prototypes of fuel cell stacks can be evaluated comparably.
- "Evaluate" in the context of this text means all methods, methods and procedures for testing, testing, testing and investigating the operation of fuel cell units, ie in the sense of a functional test or diagnosis, as well as e.g. the investigation of the operating behavior depending on certain operating conditions or external conditions.
- Another advantage is the application-oriented design of the periphery according to the invention. It can therefore be easily integrated into applications. This facilitates in particular the development of prototypes for applications of fuel cell systems. Examples of such applications are i.a. an on-board power supply for a vehicle or a system for uninterruptible power supply (so-called back-up system). Of course, the present invention is not limited to these applications.
- the peripheral of the invention can be used to connect to the peripheral of the invention.
- the peripheral of the invention can be used to connect to the peripheral of the invention.
- Fuel cell units such as fuel cell stack after production, before installation in a fully integrated fuel cell system, before commissioning or after a change in operating conditions or a break in operation, to evaluate, test and test.
- the easy handling of the system facilitates routine testing.
- the compact design reduces the cost of a site test, for example, in a remote fuel cell unit used.
- Another field of application is the use as a laboratory device for research and development. For example, prototypes of fuel cell stacks can be evaluated comparably. Potential users can quickly familiarize themselves with new types of fuel cell units by means of the peripheral according to the invention and test them under application-related conditions.
- the present invention has a clear price advantage over the test stands known from the prior art. Therefore, it is possible by means of the periphery according to the invention to develop applications for which conventional test stands are too expensive and too expensive, but so far no viable alternative was available.
- inventively embodied as self-contained unit periphery since it is easy to transport, can be used as a sub-diagnostic device, for example, for testing and maintenance at almost any location, such as decentralized fuel cell units, in particular even with remote fuel cell units.
- the periphery according to the invention is also suitable for investigating the operating behavior of a fuel cell unit under various environmental conditions. For example, the influence of humidity, dust content of air and other weather and environmental conditions can be investigated.
- the periphery formed according to the invention as a self-contained structural unit enables a variety of other applications which can only be realized with extremely high outlay or not at all with conventional test stands which are not readily transportable.
- the peripherally designed according to the invention as a self-contained unit can thus be used as a mobile test station or mobile diagnostic device for fuel cell units.
