`This listing of claims will replace all prior versions, and listings, of claims in the application.
`
`Listing of Claims:
`
`1.
`
`(Original) An electrode for an electrochemical cell, the electrode comprising electrode
`
`material disposed on a substrate, wherein the electrode material comprises electrocatalyst and a
`
`solid glass phase which binds the electrocatalyst to the substrate.
`
`2.
`
`(Currently amended) An T_he electrode according to claim 1, wherein the solid glass
`
`phase is sintered glass frit which constitutes at least lOwt% of the electrode material, preferably
`
`at least 15wt%.
`
`3.
`
`(Currently amended) An T_he electrode according to claim 1 enelaim—Z wherein the glass
`
`is a silicate or borosilicate glass.
`
`(Currently amended) An T_he electrode according to wane-ellthe—preeeel-i-ng—el-ai-ms

`5.
`
`claim 1, wherein the electrocatalyst forms an interconnected network of electrocatalyst through
`
`the electrode material.
`
`(Currently amended) An T_he electrode according to anyLene—eilthe—preeeeli-ng—el-ai-ms
`
`6.
`
`claim 1, wherein the electrode material forms a barrier on the surface of the substrate, thereby
`
`preventing contact between the electrolyte and the substrate in use.
`
`(Currently amended) An T_he electrode according to anyLene—eilthe—preeeeli-ng—el-ai-ms

`
`thereof.
`
`(Currently amended) An T_he electrode according to anyLene—eflthe—preeeeli-ng—el-ai-ms
`
`11.
`
`claim 1 wherein the coefficient of thermal expansion (CTE) of the glass differs from the
`
`coefficient of thermal expansion (CTE) of the substrate by +/-10% or less.
`
`12.
`
`(Original) A method of making an electrode for an electrochemical cell comprising
`
`applying an electrode formulation comprising electrocatalyst and glass frit to a substrate and
`
`firing the electrode formulation.
`
`13.
`
`(Currently amended) A T_he method according to claim 12 wherein the electrode
`
`formulation includes at least lOwt% of the glass frit.
`
`14.
`
