Claims

[Scope of utility model registration request]

In a battery laminate formed by alternately stacking unit cells and separators, a plurality of gas passages are formed in the fuel electrode base material of the unit cell or in the separator in contact with the fuel electrode, wherein the gas passage 1. A fuel cell characterized in that the fuel cell is provided with a throttling means whose throttling amount increases as it goes upwards in the battery stack.
