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

Abstract

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.
