Patent ID: 10862138

Abstract:
A fuel cell includes a porous support substrate and a power generation element portion. The support substrate includes a first end portion that is linked to a gas supply chamber and a gas collection portion, and a second end portion that is located opposite to the first end portion. The support substrate includes a first gas channel and a second gas channel. The first gas channel extends from the first end portion toward the second end portion. The first gas channel is connected to the gas supply chamber. The second gas channel is connected to the first gas channel on the second end portion side. The second gas channel extends from the second end portion toward the first end portion. The second gas channel is connected to the gas collection chamber. The support substrate is configured such that gas flows in the support substrate and moves between the first gas channel and the second gas channel, in a portion of the support substrate that is farther toward the first end portion side than the power generation element portion is.
