Abstract:
The present invention relates to an internal current collecting structure of a tubular thermal conversion power generation cell including an internal electrode, a solid electrolyte, and an external electrode. The internal current collecting structure comprises: a first current collector in close contact with the internal electrode of the tubular thermal conversion power generation cell; a second current collector fixing the porous first current collector inside the tubular thermal conversion power generation cell to be in close contact with the internal electrode; and a lead wire, as a conductive medium, arranged between the first current collector and the second current collector. The internal current collecting method of the thermal conversion power generation cell allows the current collector of the internal current collecting structure to come close and smooth contact with the internal electrode of the thermal conversion power generation cell. Accordingly, a problem of a conventional internal current collection can be resolved since a lead wire, which is a conductive medium, is connected to a current collector with ease.
