Abstract
In order to create a fuel cell unit, comprising a cathode-anode-electrolyte unit and a contact plate which is in electrically conductive contact with the cathode-anode-electrolyte unit, which requires only small production resources and is thus suitable for large-scale production it is suggested that the fuel cell unit comprise a fluid guiding element which is connected to the contact plate in a fluid-tight manner, forms a boundary of a fluid chamber having fluid flowing through it during operation of the fuel cell unit and is designed as a shaped sheet metal part.

Fuel cell unit, comprising:
- a cathode-anode-electrolyte unit, a contact plate in electrically conductive contact with the cathode-anode-electrolyte unit, and a fluid guiding element being formed as a shaped sheet metal part and connected to the contact plate in a fluid-tight manner by way of welding or by way of soldering, the fluid guiding element and the contact plate defining therebetween a fluid chamber having a combustible gas or an oxidation agent flowing through it during operation of the fuel cell unit.
Fuel cell unit, comprising:
- a cathode-anode-electrolyte unit, a contact plate in electrically conductive contact with the cathode-anode-electrolyte unit, and a fluid guiding element being formed as a shaped sheet metal part and connected to the contact plate in a fluid-tight manner, said fluid guiding element and said contact plate forming a two-part shell surrounding said cathode-anode-electrolyte unit of the fuel cell unit.
Fuel cell unit, comprising:
- a cathode-anode-electrolyte unit, a contact plate in electrically conductive contact with the cathode-anode-electrolyte unit, a fluid guiding element being formed as a shaped sheet metal part and connected to the contact plate in a fluid-tight manner, and an electrically insulating fluid channel seal arranged between the contact plate of the fuel cell unit and the fluid guiding element of an adjacent fuel cell unit or between the fluid guiding element of the fuel cell unit and the contact plate of an adjacent fuel cell unit, said fluid channel seal surrounding a fluid port provided in the fluid guiding element or a fluid port provided in the contact plate and said fluid channel seal being spaced apart from the electrolyte of the cathode-anode-electrolyte unit of the fuel cell unit.
Fuel cell unit, comprising:
- a cathode-anode-electrolyte unit, a contact plate in electrically conductive contact with the cathode-anode-electrolyte unit, and a fluid guiding element being formed as a shaped sheet metal part and connected to the contact plate in a fluid-tight manner, said fluid guiding element forming a boundary of a fluid chamber having fluid flowing through it during operation of the fuel cell unit and abutting on the cathode-anode-electrolyte unit via an electrically insulating seal.
