Abstract
A method of making an interconnect for an electrochemical cell column includes casting a metal alloy or a metal matrix composite material to form a near-net-shape interconnect part which includes riser openings, a fuel flow field and an air flow field, and forging the near-net-shape interconnect part to form the interconnect.
Claims20
An interconnect for an electrochemical cell column, comprising:
- an air side and an opposing fuel side;
- a fuel flow field located on the fuel side and comprising fuel channels separated by fuel ribs;
- and
- an air flow field located on the air side and comprising air channels separated by air ribs,
- wherein the interconnect comprises a metal matrix composite material.
