Abstract
A fuel cell includes a support substrate, at least one power generation element portion, at least one first gas channel, and at least one second gas channel. The power generation element portion is disposed on the support substrate. The first and second gas channels extend from a proximal end portion toward a distal end portion in the support substrate and are connected to each other at the distal end portion. The sum of a cross-sectional area of the at least one first gas channel is smaller than the sum of a cross-sectional area of the at least one second gas channel.
