Abstract:
발전기 시스템 내부에 존재하는 액상 또는 기상의 작동 유체를 이용한 집전 방식으로 액상의 작동 유체를 함침할 수 있는 금속 펠트(felt)와 같은 다공성 구조체를 셀간에 삽입하여 연결시켜, 셀 주위에 존재하는 작동 유체가 자연스럽게 함침되어 집전이 이루어지는 방식이다. 복수 개의 열전환 발전 셀 중 인접한 열전환 발전 셀 사이에 위치한다. 즉, 제 1 열전환 발전 셀, 제 1 열전환 발전 셀과 인접한 제 2 열전환 발전 셀, 제 1 열전환 발전 셀과 제 2 열전환 발전 셀사이에 위치하여 전기적으로 연결하는 집전체를 포함하는 것이 가능할 것이다. 상기 집전체로 사용되는 물질은 금속 펠트(felt)와 같은 다공성 구조체 자체도 통전성 및 완충효과가 커서 일반적인 전기적 집전체로 사용되는 물질이 가능할 것이다. 또한, 액상 금속이 다공질 내부에 흡수될 경우 웨트 컨택(wet contact)으로 셀 간 계면저항이 매우 낮아져 집전의 효과를 극대화할 수 있는 장점이 있다. 이와 함께, 복잡한 도선 구성이 필요하지 않으며, 구조물이 단순하여 대용량 구성이 용이하여 비용이 저렴하고 기계적으로 안정하며 큰 전류량에 관계없이 사용 가능한 집전 방식이다.

A flat-tubular solid oxide cell according to the present invention comprises multiple solid oxide unit cells having a first gas flow channel formed therein in a longitudinal direction, and having a gas inlet port for a first gas flowing in on one side of the first gas flow channel and a gas outlet port for the first gas flowing out on the other side of the first gas flow channel; a channel connector positioned between the gas inlet port and the gas outlet port of adjacent solid oxide unit cells, wherein the gas outlet port of one of the adjacent solid oxide unit cells is arranged to face the gas inlet port of the other, and connecting the first gas flow channels of the adjacent solid oxide unit cells; and a ring-shaped compressed sealing gasket interposed between the mutually facing gas inlet port and gas outlet port, and the channel connector to prevent leakage of the first gas.
Abstract:
The present invention relates to an elastic current collector and a current collecting method for a tube-shaped cell. Current is collected from the inner electrode of a tube-shaped cell by using, as a current collector, an elastic structure having the shape of a spring coil, a tube-shaped mesh, a tree, and a roll-shape mesh instead of using a traditional cylindrical current collector. Not only the current collector is economical by reducing weight thereof but also current collecting efficiency can be increased by minimizing interfacial resistance between the inner electrode and the current collector via the elasticity of the current collector. Therefore, the present invention relates to a conductive elastic current collector capable of increasing the efficiency of a cell and to a current collecting method for a tube-shaped cell.
