An apparatus of solid oxide fuel cells (SOFC) is provided. The SOFCs generate power and are grid-tied. The apparatus comprises a power-generating side; and a grid-connecting side using an elementary household power management. The apparatus solves problems like low voltage, high current, voltage oscillation, voltage dips, long generator-starting time, etc. The apparatus is not only used as a stable power supply (base load), but also helps adjust the regional peak electricity demands. The features include the following: 1. A grid is tied, where output power does not pass through a direct-current boost converter and, thus, has no loss from it. 2. Injures, including voltage oscillation and sudden unloading after dumping, are reduced for avoiding further damages to cell sheets. 3. With the coordination of elementary power management and the integration of grid, the limitation of long-awaiting generator-starting time is crossed out and convenience of immediate power use is achieved.

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.
