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.
