Abstract

A technique includes operating a fuel cell, which produces an effluent flow. The technique includes routing the effluent flow through an electrochemical pump to extract fuel from the effluent flow to produce a first feedback flow. The technique includes using the effluent flow to produce a second feedback flow separate from the first feedback flow and routing the second feedback flow through a venturi to the fuel cell.
