Abstract
The present invention aims to reduce a failure in a fuel cell module and reduce manufacturing costs by specifying and taking countermeasures against cells in short-circuit failure from among fuel cells manufactured on a substrate by using a thin-film deposition process. In a fuel cell array according to the present invention, each fuel cell includes a solid electrolyte layer between a first electrode layer and a second electrode layer. A first wiring is connected to the second electrode layer, and a second wiring is connected to the first electrode layer through a connection element. The connection element is formed by sandwiching a conductive layer between two electrodes (refer to FIG.).
