Abstract: A testing device for solid oxide fuel cell (SOFC) is disclosed. The testing device which combines the original cell housing with a four-point probe equipment is set for measuring SOFC MEA. The current collectors on anode and cathode in the original cell housing are respectively replaced by four independent probe units. They are not only to collect current but also to become measuring probes. Therefore, the lateral impedance of anode and cathode can be measured. Furthermore, the local characteristics are examined by open circuit voltage (OCV), I-V curve, and electrochemical impedance spectroscopy (EIS) measurements. The results show that the lateral impedance is substantially varied with temperatures. The distributions of OCV, current density, EIS and cell voltage in long-term test at the center of the cell are different from the edge.

Abstract: A burner reformer is provided for a power generating system using fuel cell. A burner is contained inside the reformer. The reformer absorbs heat from the burner and other heat source to reduce heat loss and save connecting wires. The present invention avoids flashing back of hydrogen. When fuel is lean, flame would not easily die and the system can thus work stably.

Abstract: A gas-reforming catalyst is modified to obtain stability in high temperature. The catalyst uses ?-Al2O3 as a carrier and is nano-porous. Hence, reaction surface is greatly broadened; and platinum contained inside does not become bigger after times of use. The catalyst does not deposit carbon and has long life. The stability of the catalyst can be still remained even at a temperature higher than 800° C.
