Embodiment Construction

[0029] As required, detailed embodiments are disclosed herein; however, it should be understood that the disclosed embodiments are representative only and may be embodied in various alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the claimed subject matter.

[0030] In the various figures, identical parts are always provided with the same reference numerals, and are therefore usually also described only once.

[0031] figure 1 is a block diagram of a representative embodiment of a fuel cell operating method or system 1 according to the present disclosure. A fuel cell method or system 1 includes a fuel cell stack 2 having a plurality of fuel cells ( figure 2 ), stack anode 3...

Abstract

A system and method for generating vibrations in a fuel cell system include a vibration device which can be arranged on the fuel cell system or is formed by at least one component of the fuel cell system, for generating excitation vibrations which can be transmitted to the component. An electronic actuating system includes a controller and memory for actuating the vibration device, which may include a coolant pump or a compressor, at a natural frequency of a fuel system component for de-icing. At temperatures below 0 DEG C., the electronic actuating system is adapted to actuate the vibration device during a switch-on process and / or a switch-off process of the fuel cell system taking into consideration at least one natural frequency of the component. Embodiments including actuating a compressor, cooling pump, and / or valve to transmit vibrations to a component to be de-iced at a natural frequency of the component.

Description

technical field [0001] The present invention relates to a system and method for generating vibrations on at least one component of a fuel cell system to reduce or eliminate ice. Background technique [0002] In order to be able to start and operate the fuel cell system at temperatures below 0°C, especially the fuel cell channels and fuel cell connections must be free from ice blockages. Due to insufficient hydrogen supply and / or insufficient oxygen supply, this ice blockage can at best cause interruption of the start-up process, and at worst damage some or all of the fuel cells of the fuel cell system. Various measures have been proposed to prevent the formation or destruction of such ice blocks. [0003] US 2013 / 0095406 A1 discloses a method and system for improving fuel cell efficiency by removing obstructions within fuel cell channels. The system includes at least one sensor and a processor for determining when a concentration level of a gas, such as carbon dioxide, exc...
