Abstract:
1. A fuel cell system, comprising: a fuel conversion reactor formed in a plate shape and comprising a channel providing a space for a fuel conversion reaction; an inlet of the fuel conversion reactor fluidly connected to the channel and configured to receive one or more reactants of the fuel conversion reaction; and an outlet of the fuel conversion reactor fluidly connected to the channel and configured to discharge resultants of the fuel conversion reaction, wherein the channel has a cross-sectional size taken in a plane where the cross-sectional size is the smallest at a first portion of the channel, wherein the channel has a second portion, in which the cross-sectional size varies along the channel, wherein the channel is branched into two or more sub-channels that terminate at the outlet, and wherein a ratio of a sum of opening cross-sectional sizes of sub-channels at the outlet to a cross-sectional size of an inlet opening is between about 1.5 and about 3, and wherein the fuel cell system further comprises fuel cells configured to generate electricity using at least one of the resultants.
