摘要:
In a fuel cell comprising a stack having superposed a plurality of electromotive parts composed of a fuel electrode, an oxidizing electrode, and an electrolyte layer nipped by the two electrodes and using a liquid fuel as the fuel for the fuel cell, this invention contemplates forming a liquid fuel introducing path destined to be directly exposed to the liquid fuel on terminal surfaces of the component parts of the electromotive parts in a direction perpendicular to the flow of an oxidizing gas along at least one of the outer peripheral surfaces of the stack including the terminal surface of the fuel electrode and lying parallelly to the flow of the oxidizing gas and enabling the liquid fuel in the liquid fuel introducing path to be supplied to the fuel electrodes by a capillary attraction. A fuel cell provided with means for recovery of the water produced by the cell reaction in the oxidizing electrodes is also disclosed, which fuel cell effects the removal of the water produced in the oxidizing electrodes during the operation of the fuel cell by a capillary attraction generated by two porous members.

A fuel cell provided with means for recovery of the water produced by the cell reaction in the oxidizing electrodes is also disclosed, which fuel cell effects the removal of the water produced in the oxidizing electrodes during the operation of the fuel cell by a capillary attraction generated by two porous members, i.e. a first porous member disposed in the oxidizing electrodes and a second porous member adjoined to the first porous member and possessed of a smaller average pore diameter than the first porous member.
