c is used as the oxidizing medium this method permits the use of less than 5 weight percent chromium in nickel alloy electrodes while obtaining good resistance to creep in the electrodes of a fuel cell stack application_number US 82371886 A description in one manner of preparing the anode structure of the present invention an alloy of nickel with low chromium content is formed although other methods may be used powder metallurgical techniques conveniently are selected in preparing the porous anode structure compacted powders of uniformly mixed nickel and chromium in the desired proportions are formed to promote a uniform mixture the nickel and chromium particles preferrably are provided of about the same particle size for example particles sizes in the range of 1 100 microns can be selected for use the compact of mixed nickel and chromium powder is sintered and heat treated at elevated temperature to uniformly diffuse the chromium into the nickel and thereby form a nickel chromium alloy it has been found that temperatures of about 1000 u00b0 1100 u00b0 c for 5 90 minutes preferrably about 1050 u00b0 c for about 15 minutes can be used to form a uniform alloy of nickel and chromium at about the 1 4 by weight chromium level it is of considerable importance that a uniform alloy be formed in order to obtain the uniform and consistent dispersal of the subsequently oxidized chromium particles within the porous nickel structure pockets rich.
