The PoE technique is put forward officially by IEEE by defining a criterionnamed of 802.3af in June 2003, which allow transmitting direct voltage throughcommunication cables. The issue of PoE criterion helps to realize the method oftransmitting electronic power via communication cables, which will dramaticallysimplify the network facility construction, and expand the scope of networkapplicati...

Solid Oxide Fuel Cell (SOFC), as a new way of power generation, exhibits a great potential in solution of energy crisis and environmental pollution, and gets a wide attention in recent year. SOFC is composed by cathode, electrolyte, anode and interconnect. From the viewpoint of the high electrical conductivity, low reactivity and good compatibility with YSZ, La1-xSrxMnO3(LSM)is considered to ...
