Definitions
- the invention relates to a fuel cell system with at least one heat-generating component and at least one component using process air.
- the invention further relates to a method for influencing the heat balance of a fuel cell system.
- Fuel cell systems serve to generate electrical energy and heat energy, with the primary supply of fossil fuels becoming increasingly important.
- the fuels used are preferably used, while in stationary use, that is to say in particular in the domestic sector, natural gas and fuel oil are used.
- waste heat generated by a DC / DC or a DC / AC converter can also be regarded as a power loss of the fuel cell system.
- the excessive waste heat reduces the efficiency of the system, and on the other hand, it can also be undesirable as such, for example when operating a fuel cell system for air conditioning on hot days.
- the invention has for its object to provide a fuel cell system with reduced heat losses and improved thermal management available.
- the heat-generating component is arranged in a housing and the ambient air can be supplied to an inner region of the housing.
- the housing allows a plurality of heat generating components and the sewerage of the supplied ambient air in such a way that the heat release of all heat generating components can contribute to the heating of the supplied ambient air.
- a heat-generating component is arranged outside of a housing in which further heat-generating components are arranged.
- a housing in which further heat-generating components are arranged.
- the housing is a thermal insulation device.
- This isolation device can be the isolation device provided anyway anyway mostly around the heat generating components of the fuel cell system or an additional isolation device, which is arranged around the already provided isolation device around. in the In the latter case, the air guide will then take place between the conventional isolation device and the additional isolation device.
- the at least one heat-generating component is a reformer and / or an afterburner and / or a fuel cell assembly and / or a media guide and / or a DC / DC converter.
- the supplied ambient air is first heat-supplying components with a first temperature can be supplied and subsequently heat-generating components with a second temperature can be fed bar, wherein the first temperature is lower than the second temperature. Since the speed of the heat transfer depends on the temperature difference of the media involved, it makes sense initially to apply cold air to the cooler components in order to provide a relatively large temperature difference here as well. Already heated air can subsequently be supplied to warmer components, a correspondingly high temperature difference also being present then. Thus, all components can equally be included in the temperature management of the fuel cell system.
- the ambient air can be supplied by the delivery of a blower associated with the component using process air.
- a blower associated with the component using process air no additional blower for the introduction of the ambient air is required.
- the component using the process air is a reformer and / or an afterburner and / or a fuel cell arrangement.
- the invention further relates to a method for influencing the heat balance of a fuel cell system according to the invention.
- Figure 1 is a schematic representation of a conventional fuel cell system
- Figure 2 is a schematic representation of a first embodiment of a fuel cell system according to the invention.
- Figure 3 is a schematic representation of a second embodiment of a fuel cell system according to the invention.
- FIG. 1 shows a schematic representation of a conventional fuel cell system.
- the typical fuel cell system 10 shown here includes a plurality of components that are partially disposed within an isolation device 38.
- the reformer 12 is supplied via a fuel feed 18 from a fuel pump 42 funded fuel and air via an air feed 20 from a blower 40 conveyed air.
- the hydrogen-rich reformate prepared in the reformer 12 then passes via a reformate line 26 to the anode side of a fuel cell stack 14, wherein the fuel cell stack 14 is further supplied with air via a cathode inlet line 22 and an associated fan 44.
- Anode exhaust of Brennstoffzellenan- order 14 passes via an anode exhaust gas line 28 in an afterburner 16, which is also supplied via an air supply line 24 and an associated fan 46 air.
- the exhaust gases generated in the afterburner 16 exit from the fuel cell system 10 via an exhaust gas line 30.
- the power generated by the fuel cell system 14 is supplied to a converter 32, for example a DC / DC or a DC / AC converter.
- the fuel cell system 10 shown in this way allows numerous variants, for example, exhaust gas can be recirculated from the afterburner 16.
- cathode exhaust air from the fuel cell assembly 14 may be supplied to the afterburner 16.
- heat exchangers can be provided which permit a variety of heat exchange between different media streams in a variety rich variety.
- the problem with such fuel cell systems 10 is the heat loss. This is done on the one hand naturally on the isolation device 38, which is indicated by the arrows 48, 50, and in particular in the range of bushings through the isolation device 38, for example in the range of media feeds, which is indicated by the arrow 52nd is indicated. Further heat losses occur at the transducer 32, indicated by the arrow 54.
- FIG. 2 shows a schematic representation of a first embodiment of a fuel cell system according to the invention.
- a housing 36 which is equipped with at least one air inlet opening 56 for the entry of ambient air 34.
- an air outlet opening 58 is provided, which is coupled to the air inlet side of the blower 40.
- the heat-generating components of the fuel cell assembly 10 are housed.
- ambient air 34 is now sucked into the housing 36, which then flows around the isolation device 38 or the converter 32 arranged outside the isolation device 38.
- the cold ambient air 34 absorbs heat and leaves in the heated state via the air outlet opening 58, the housing 36.
- the heated ambient air is supplied via the blower 40 to the reformer 12 again as process air. It is also possible to supply the heated air alternatively or additionally to the fuel cell stack 14 or to the afterburner 16.
- FIG. 3 shows a schematic representation of a second embodiment of a fuel cell system according to the invention. According to this embodiment, it is provided to equip the isolation device 38 itself with an air supply opening 56 and an air outlet opening 58.
- the cool ambient air flows around directly the components, such as the afterburner 16, the Brennstoffzellensta- pel 14 and the reformer 12, and then in the heated state and after exiting the air outlet opening 48 via the blower 40 to the reformer 12 to be recycled as process air.
- Such a design of the system does not require an additional outer housing 36 (see FIG. 2). Also, due to the heat energy dissipated by the transducer 32, a separate warm air return device would be required.
