Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. If not specifically defined or elucidated, 'upper', 'lower', 'left' and 'right' are used herein to describe directions based on the drawings. Furthermore, like reference numerals designate like elements in all embodiments.

[0036] A typical fuel cell consists of a fuel processor (reformer and reactor) that reforms and provides fuel, and a fuel cell module. A fuel cell assembly includes a stack of fuel cells that utilize electrochemical reactions or processes to convert chemical energy into electrical and thermal energy. That is, in one embodiment, the fuel cell assembly includes: a fuel cell stack (fuel cell stack); a pipe system through which fuel, oxides, cooling water, and effluent flow; wires, The electricity generated by the stack is conducted through the wires; the components of the stack are controlled or monitored; and the components that handle an...

Abstract

Provided in the invention is a tubular fuel cell module having improved current collecting efficiency. In one embodiment, the fuel cell module includes: a fuel cell unit; a first current collector extending along an outer side of the fuel cell unit; and a second current collector wound around the first current collector and around the outer side of the fuel cell unit. Here, the outer side of the fuel cell unit is a curved outer side, the first current collector has a curved inner side facing the curved outer side of the fuel cell unit, and the curved inner side of first current collector is shaped to match the curved outer side of the fuel cell unit.

Description

technical field [0001] The following description relates to a fuel cell module, in particular, to a fuel cell module having a structure capable of increasing its current collection efficiency. Background technique [0002] Since fuel cells have various output ranges and uses, a fuel cell suitable for a specific purpose can be selected. Among fuel cells, solid oxide fuel cells for distributed power generation, commercial and home use have attracted much attention because these fuel cells have the following advantages: the position control of the electrolyte is relatively easy; since the position of the electrolyte is fixed, the electrolyte is hardly is exhausted; and the material has a long life due to the high corrosion resistance. In addition, solid oxide fuel cells are cells that operate at relatively high temperatures of about 600-1000°C, and have several advantages: they have the highest efficiency and result in less air than various fuel cells of the related art pollu...
