A fuel cell collector structure of the present invention includes a single cell which is formed by sandwiching a plate-shaped solid electrolyte between a fuel electrode and an air electrode, a collector which is provided at a position adjacent to the single cell, and a separator which is provided at the position adjacent to the collector. In some embodiments, a terminal server sends a new channel request to a terminal server. The set of guide pins have proximal and distal ends extending through the set of apertures in the planar substrate. A second polishing step is performed to remove a portion of the remaining portion of the silicon oxide layer until the silicon nitride layer is exposed.
