| 摘要 |
Fuel cell devices are provided having improved shrinkage properties between the active and non-active structures by modifying the material composition of the non-active structure, having a non-conductive, insulating barrier layer between the active structure and surface conductors that extend over the inactive surrounding support structure, having the width of one or both electrodes progressively change along the length, or having a porous ceramic layer between the anode and fuel passage and between the cathode and air passage. Another fuel cell device is provided having an internal multilayer active structure with electrodes alternating in polarity from top to bottom and external conductors on the top and/or bottom surface with sympathetic polarity to the respective top and bottom electrodes. A fuel cell system is provided with a fuel cell device having an enlarged attachment surface at one or both ends, which resides outside the system's heat source, insulated therefrom.
