FUEL CELL SYSTEM

摘要

In some examples, solid oxide fuel cell system including a tubular substrate defining a fuel flow cavity within the tubular substrate; a plurality of solid oxide fuel cells on a surface of the tubular substrate, each cell including an anode electrode, a cathode electrode, and electrolyte, wherein the anode electrode, cathode electrode, and electrolyte are configured to form an electrochemical cell, wherein, during fuel cell during operation, fuel flows within the fuel flow cavity of the tubular substrate along a fuel flow direction from an inlet to an outlet of the fuel flow cavity, and wherein a permeability of the tubular substrate to the fuel varies along the fuel flow direction.
