Stable electrolyte matrix for molten carbonate fuel cells

Patent Hilmi, Abdelkader; Surendranath, Arun; Yuh, Chao-Yi; ...

An electrolyte matrix for use with molten carbonate fuel cells having an enhanced stability and lifetime is provided. The electrolyte matrix includes lithium aluminate as a support material and a coarsening inhibitor. The coarsening inhibitor may be in the form of discrete particles or a dopant present in the support material. The coarsening inhibitor may include MnO₂, Mn₂O₃, TiO₂, ZrO₂, Fe₂O₃, LiFe₂O₃, or mixtures thereof. The coarsening inhibitor prevents the formation of large pores in the electrolyte matrix during operation of the fuel cell, increasing the performance and the service lifetime of the electrolyte matrix.

Electrolyte matrix for molten carbonate fuel cells

Patent Huang, Chao M [Danbury, CT]; Yuh, Chao-Yi [New Milford, CT]

A matrix for a carbonate electrolyte including a support material and an additive constituent having a relatively low melting temperature and a relatively high coefficient of thermal expansion. The additive constituent is from 3 to 45 weight percent of the matrix and is formed from raw particles whose diameter is in a range of 0.1 .mu.m to 20 .mu.m and whose aspect ratio is in a range of 1 to 50. High energy intensive milling is used to mix the support material and additive constituent during matrix formation. Also disclosed is the use of a further additive constituent comprising anmore » « less

Binder for electrolyte matrix for molten carbonate fuel cells

Patent Surendranath, Arun; Hilmi, Abdelkader; Yuh, Chao-Yi

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.

Electrolyte matrix in a molten carbonate fuel cell stack

Patent Reiser, Carl A [Glastonbury, CT]; Maricle, Donald L [Glastonbury, CT]

A fuel cell stack is disclosed with modified electrolyte matrices for limiting the electrolytic pumping and electrolyte migration along the stack external surfaces. Each of the matrices includes marginal portions at the stack face of substantially greater pore size than that of the central body of the matrix. Consequently, these marginal portions have insufficient electrolyte fill to support pumping or wicking of electrolyte from the center of the stack of the face surfaces in contact with the vertical seals. Various configurations of the marginal portions include a complete perimeter, opposite edge portions corresponding to the air plenums and tab sizemore » « less
