摘要:
An in-line planar fuel cell height measurement system is mainly composed of a main stand, at least a top platform above a high temperature furnace, a displacement detection unit on the top platform with a central axis connecting to an extension rod that goes downward into the high temperature furnace and contacts the top surface of the cell stack inside the high temperature furnace, a displacement display unit connecting to the displacement detection unit through signal transmission cables, and a data processing unit connecting to the displacement display unit through signal transmission cables, so the displacement detection unit can sense the height change for the cell stack in the high temperature furnace during temperature rise and operation and send out a signal, which can be directly displayed by the displacement display unit and received by a data processing unit for further analysis and storage.

A load device for planar solid oxide fuel cell stack comprises: a balance plate, a high-temperature compressed column, a load cell, an elastic member, an equalizing ring, and an actuator. The balance plate is disposed abutted against the fuel cell stack, and the high-temperature compressed column is disposed on the balance plate, and the load cell and the elastic member are arranged at a top portion of the high-temperature compressed column. The actuator, being placed on the equalizing ring, is used for providing a load to the equalizing ring, the load cell, the elastic member and the high-temperature compressed column Thereby, the load exerted by the actuator can be detected from the measurement of the load cell while the relationship between the load variation and performance of the SOFC stack can be read directly or transmitted to an external device for display.

A plate type fuel reformer of fuel cells includes a reformer module stacked by multiple sheet components, and an engaging surface formed on a surface of the reformer module and adhered to a surface of the default fuel cell module in order to form a great thermally-conductive combination. Detachable connections are formed between each of the sheet components and between the sheet components and the fuel cells module. The edge of the reformer module is non-protruding from the side of the fuel cell module after connection. Multiple containing spaces are respectively formed between each of the sheet components for containing default catalyst units. Also, an independent air channel is formed for guiding outside air to into the fuel cell module and a fuel channel is formed for containing the default catalyst units and guiding outside fuel to react with the catalyst units to generate hydrogen gas and carbon monoxide.
