Abstract
A method of making a fuel cell stack includes applying an electrically conductive, compliant contact print ink containing an electrically conductive material, a plasticizer, a solvent, and a binder to at least one of a surface of an electrode of a fuel cell or a surface of an interconnect, and placing the fuel cell and the interconnect in the fuel cell stack such that the compliant contact print ink is located between the electrode of the fuel cell and the interconnect.
Claims11
A method of making a fuel cell stack, comprising:
- applying an electrically conductive, compliant contact print ink comprising an electrically conductive material, a plasticizer, a solvent, and a binder to at least one of a surface of a cathode electrode of a fuel cell or a surface of an interconnect, wherein the electrically conductive material comprises at least one of lanthanum strontium manganite (LSM), lanthanum strontium cobaltite (LSC), lanthanum strontium ferrite (LSF), or manganese cobalt oxide (MCO);
- and
- placing the fuel cell and the interconnect in the fuel cell stack such that the compliant contact print ink is located between and contacts the cathode electrode of the fuel cell and the interconnect.
A method of making a fuel cell stack, comprising:
- applying an electrically conductive, compliant contact print ink comprising an electrically conductive material, a plasticizer, a solvent, and a binder to at least one of a surface of a cathode electrode of a fuel cell or a surface of an interconnect;
- and
- placing the fuel cell and the interconnect in the fuel cell stack such that the compliant contact print ink is located between and contacts the cathode electrode of the fuel cell and the interconnect;
- wherein the plasticizer comprises diacetylated monoglyceride and the compliant print ink comprises from about 20 weight percent to about 50 weight percent of the plasticizer, based on a total weight percent of the binder included in the compliant print ink.
