Abstract
A binder solution for an electrolyte matrix for use with molten carbonate fuel cells is provided. The binder solution includes a first polymer with a molecular weight of less than about 150,000 and a second binder with a molecular weight of greater than about 200,000. The binder solution produces an electrolyte matrix with improved flexibility, matrix particle packing density, strength, and pore structure.
Claims13
A green electrolyte matrix, comprising:
- a support material;
- an electrolyte material;
- and
- a binder,
- wherein the binder comprises a first polymer with a molecular weight of less than 150,000 and a second polymer with a molecular weight of greater than 200,000;
- and
- wherein the green electrolyte matrix is configured to be installed in a fuel cell;
- and
- wherein the binder is configured to be removed from the green electrolyte matrix when the fuel cell is initially conditioned, so as to define an electrolyte matrix that is free of pores with a size of 0.2 μm or greater.
