Embodiment Construction

[0032] exist figure 1 A gear mechanism 1 with a housing 2 and two meshing gears 3 is schematically shown in FIG. The gear mechanism 1 has an inlet 4 on the high-pressure side and an outlet 5 on the low-pressure side.

[0033] When fuel or hydrogen flows through the gear mechanism 1 , the gear 3 rotates in the direction of the arrow shown in the drawing.

[0034] exist figure 2 Shown in is a schematic representation of a gear mechanism system with multi-stage pressure expansion. The distribution unit 6 here distributes the fuel to, for example, three gear mechanisms 1 arranged on a common transmission shaft 7 . The transmission shaft 7 can be connected to a generator for generating electrical energy, which is not shown in detail.

[0035] A heat exchanger 8 or a heating unit 8 , respectively, can be arranged between the gear mechanism 1 in order to add some heat to the cooled fuel or hydrogen due to the expansion. The cooling of individual components, which are not shown ...

Abstract

One kind of fuel equipment with fuel cell unit and / or internal combustion engine is proposed, and the fuel equipment is provided with one fuel supply device to provide the fuel cell unit and / or internal combustion engine with fuel. The fuel supply device includes at least one pressure energy utilizing unit for converting and utilizing the pressure energy of the fuel, and the pressure energy utilizing unit may be made with simple structure and low cost. The pressure energy utilizing unit of the present invention is used to generate mechanical energy and includes at least two gear mechanisms.

Description

technical field [0001] The invention relates to a fuel plant with a fuel cell unit and / or an internal combustion engine according to the preamble of claim 1 , wherein a fuel system for feeding pressure-loaded fuel to the fuel cell unit and / or internal combustion engine is provided. Supply device. Background technique [0002] Interest in hydrogen as a future energy carrier has clearly increased through the open discussion of novel automotive drives with reduced emissions, such as zero-emission vehicles (ZEV), conservation of fossil resources, etc. Hydrogen can be converted, for example, either in an internal combustion engine or in a fuel cell. In the fuel cell, the chemical combination energy is directly converted into electrical energy, which is again converted into mechanical drive energy by means of an electric motor. [0003] Hydrogen is in principle produced renewable, as well as free of harmful substances and free of CO 2 Possibility of burning or converting. In a...
