Abstract
In a fuel cell including an electrolyte layer allowing an anion component to migrate, and a fuel-side electrode and an oxygen-side electrode arranged to face each other while sandwiching the electrolyte layer, the oxygen-side electrode contains a first catalyst containing a first transition metal and polypyrrole, and a second catalyst containing a second transition metal and a porphyrin ring-containing compound so that the mixing ratio of the first catalyst relative to 100 parts by mass of the total amount of the first catalyst and the second catalyst is more than 10 parts by mass, and below 90 parts by mass.
