Claims
- 1. A fuel cell comprising:
- a stacked body comprising
- a fuel electrode, an oxidizing electrode, and an electrolyte plate nipped between said fuel electrode and said oxidizing electrode;
- means for supplying a fuel to said stacked body;
- means for supplying an oxidizing agent to the stacked body; and
- means for recovering water generated at said oxidizing electrode, wherein said recovering means comprises a first water absorbing means adjoined to said oxidizing electrode and second water absorbing means adjoined to said first water absorbing means and provided externally of said stacked body, wherein said second water absorbing means has a higher water absorbing ability than said first water absorbing means.
- 2. A fuel cell according to claim 1, wherein said first water absorbing means is composed of a porous material, said second water absorbing means is composed of a porous material, and said second water absorbing means have a smaller average pore diameter than said first water absorbing means.
- 3. A fuel cell according to claim 1, wherein said fuel cell is operated at a temperature of about 100.degree. C. or below.
- 4. A fuel cell according to claim 1, wherein said fuel cell is a solid polymer electrolyte fuel cell.
- 5. A fuel cell comprising:
- a plurality of electromotive parts comprising a fuel electrode, an oxidizing electrode, and an electrolyte layer nipped between said fuel electrode and said oxidizing electrode, said plurality of electromotive parts being connected in series,
- wherein a fuel is supplied from a common fuel path to said fuel electrodes of said plurality of electromotive parts, the surfaces of said fuel electrodes of said plurality of electromotive parts confronting with said common fuel supplying path, and said electrolyte layer comprises a water absorbing substance and/or water retaining substance.
- 6. A fuel cell comprising:
- a plurality of electromotive parts comprising a fuel cell, an oxidizing electrode, and an electrolyte layer nipped between said fuel electrode and said oxidizing electrode, said plurality of electromotive parts being connected in series,
- wherein an oxidizing agent is supplied from a common oxidizing agent path to said oxidizing electrodes of said plurality of electromotive parts, the surfaces of said oxidizing electrodes of said plurality of electromotive parts confronting with said common oxidizing agent supplying path, and said electrolyte layer comprises a water absorbing substance and/or water retaining substance.
