Abstract:
1. A tubular fuel cell, comprising: a plurality of center support members that serve as an internal collector forming gaps therebetween for reaction gas flow paths, the plurality of center support members including wire rods; an electrolyte layer surrounding the center support member; a plurality of outer circumferential support members disposed between the center support members and the electrolyte layer, each of the plurality of outer circumferential support members being a wire rod; a catalyst layer disposed on an outer circumferential surface of each of the plurality of outer circumferential support members, the catalyst layer being in contact with the electrolyte layer; and a plurality of auxiliary outer circumferential support members disposed between the plurality of center support members and the plurality of outer circumferential support members, each of the auxiliary outer circumferential support members being a wire rod and being wound around the plurality of center support members in a first direction such that each of the auxiliary outer circumferential support members laterally abuts adjacent auxiliary outer circumferential support members on opposite sides thereof, wherein each of the plurality of outer circumferential support members is wound around the plurality of auxiliary outer circumferential support members in a second direction such that each of the outer circumferential support members laterally abuts adjacent outer circumferential support members on opposite sides thereof, and wherein a diameter of each of the plurality of center support members is greater than a diameter of each of the plurality of auxiliary outer circumferential support members.
