Two microtubular solid oxide fuel cells(μ-TSOFC)stacks are assembled using silver wires/paste in series and parallel connections．A silver based current collector mounted on an anodic rectangle window has been developed for obtaining very low Ohmic contact and is commercially available．The solid oxide fuel cell stack(SOFC)with anode support is sintered at 1 400 ℃ with an outer diameter anode tube of 5．8 mm and a 10 μm thick electrolyte．When operating at 650 ℃，the stack electrically connected in series shows an open circuit voltage(OCV)of approximately 2 V and a maximum output power(MP)of approximately 8．57 W，

whereas the stack electrically connected in parallel shows an OCV of 1．03 V，and the value of MP reaches 7．06 W，which can power the light，fan，and binding post，among other appliances．Additionally，both stacks are operated for 5 h to determine their long-term stability，and the results shows that series/parallel-connected stacks have excellent durability for an experiment． This laboratory experiment is developed to enhance students’operational ability and show them the real application of electrochemistry．
