Patent Images
1. A methanol fuel cell comprising:
- a positive electrode which has two major surfaces, the first major surface lying in direct contact with an oxygen-containing gas;
a hydrogen ion- and/or hydronium ion-conductive solid film which has two major surfaces, the first major surface lying in close contact with the second major surface of said positive electrode, and which has a methanol permeability coefficient of at most 1×
10-6 mol/(mol/l).min.cm2 ;
a negative electrode which has two major surfaces, the first major surface lying in close contact with the second major surface of said solid film; and
methanol fuel which lies in direct contact with the second major surface of said negative electrode.

Abstract
A methanol fuel cell wherein a positive electrode and a negative electrode are disposed in contact with a solid film which exhibits a hydrogen ion- and/or hydronium ion-conductivity.
The methanol permeability coefficient of the solid film of the methanol fuel cell is at most 1×10-6 mol/(mol/l).min.cm2.
