A fuel cell including an electrolyte layer having high durability is provided. In a fuel cell (1), an electrolyte layer (4), a fuel-side electrode (2) to which liquid fuel is supplied, and an oxygen-side electrode (3) to which oxygen is supplied are arranged opposite to each other with the electrolyte layer (4) interposed therebetween. The layer 4 does not have an ion exchange group and is made of a hydrophilic polymer film. [Selection] Figure 1 |
