1. A method of synthesizing a supported catalyst, the method comprising:
(a) forming a support comprising: (i) a base metal oxide selected from the group consisting of transition metal oxides, rare earth metal oxides, alkaline earth metal oxides, and post-transition metal oxides, and (ii) at least one transition metal oxide or rare earth metal oxide different from the base metal oxide;
(b) after (a), depositing nickel onto the support to form a thermally stable core;
(c) forming a catalyst tablet from the thermally stable core; and
(d) after (c), coating the catalyst tablet with an electrolyte repelling layer, the electrolyte repelling layer comprising at least one of graphite, a metal carbide, or a metal nitride, wherein the electrolyte repelling layer completely encapsulates the catalyst tablet.
