Abstract
An electrolyte-electrode assembly for high temperature fuel cells in which the electrolyte member is adapted to exhibit a more gradual transition in coefficient of thermal expansion in going from the anode electrode to the inner electrolyte region and in going from the cathode electrode to such inner electrolyte region.
Claims20
An electrolyte-electrode assembly for use in a high-temperature fuel cell comprising:
- an anode electrode comprised of a first material;
- a cathode electrode comprised of a second material;
- an electrolyte member situated between said anode and cathode electrodes and having an inner region and first and second regions on opposite sides of said inner region facing said anode and cathode electrodes, respectively, said first region having a thermal coefficient of expansion between the coefficients of thermal expansion of said anode electrode and said inner region and said second region having a coefficient of thermal expansion between the coefficients of thermal expansion of said cathode electrode and said inner region.
