Fuel cell stack system, channel structure, fuel cell, electrode and electronic device

摘要

A fuel cell stack system is configured to uniformly supply a fuel or an electrolytic solution to each of fuel cell elements, and an electronic device using the fuel cell stack system are provided. An electrolytic solution channel allowing an electrolytic solution to flow therethrough is arranged between a fuel electrode and an oxygen electrode, and a fuel channel allowing a fuel to flow therethrough is arranged outside of the fuel electrode. The electrolytic solution channels and the fuel channels of all fuel cell elements are connected in series to one another. That is, the fuel or the electrolytic solution emitted from an outlet of the fuel channel or the electrolytic solution channel of one fuel cell element enters into an inlet of the fuel channel or the electrolytic solution channel of the next fuel cell element through a connection channel. In addition, either or both of the electrolytic solution channels and the fuel channels of some or all of the fuel cell elements may be connected in series to one another.

主权项

1. A fuel cell stack system comprising a plurality of fuel cell elements,
wherein each of the plurality of fuel cell elements includes: a fuel electrode and an oxygen electrode which are arranged so as to face each other; an electrolytic channel arranged between the fuel electrode and the oxygen electrode and in contact with both the fuel electrode and the oxygen electrode, the electrolytic channel enabling an electrolytic solution to flow therethrough; and a fuel channel arranged on a side of the fuel electrode opposite to a side where the oxygen electrode is arranged and enabling a fuel to flow therethrough, wherein at least one of the electrolytic channels and the fuel channels of some or all of the plurality of fuel cell elements are connected in series to one another, and wherein the electrolytic channel comprises a channel formed in a resin sheet.
