Compliant, strain tolerant interconnects for solid oxide fuel cell stack

19 The assembly of claim 1, wherein said compliant superstructure is shaped to include at least one substantially sinusoidal channel.

An interconnect for a solid oxide fuel cell, comprising:

• a compliant superstructure having a first portion defining a separator plate contact zone and a second portion defining an electrode contact zone, wherein the superstructure is porous to operating fuel cell gaseous materials.

A solid oxide fuel cell stack comprising:

• at least three fuel cell assemblies in electrical contact, wherein at least one fuel cell assembly comprises an electrode, a separator plate, and a compliant interconnect positioned between the electrode and the separator plate, the compliant interconnect comprising a compliant superstructure having a first portion defining a separator plate contact zone and a second portion defining an electrode contact zone, wherein the superstructure is porous to operating fuel cell gaseous materials.
