Abstract
The fuel cell disclosed in the present specification is provided with an electrolyte membrane comprising a three-dimensional structure composed of bridged chains of a first polymer stable to water, and a second polymer having a function as an electrolyte. In such an electrolyte membrane, the bridged chains of the first polymer hold the second polymer, and hence the membrane does not swell with water. Furthermore, the electrolyte membrane can be properly designed depending on conditions required of the fuel cell, by choosing the first and second polymers.
