An electrochemical generator apparatus (30) is constructed containing an electrochemical cell assembly which contains a plurality of electrochemical cells or cell bundles (41) and (43) and insulation materials in the form of at least one of porous partition boards (33) between cell bundles, porous generator insulation (44), porous cell support boards (45), porous fuel entry distribution boards (35), and porous fuel conditioner boards (53), where a gaseous fuel (46) containing hydrocarbons will contact the insulation materials, characterized in that at least one of the insulation materials is impregnated with metal atom containing material, where the metal is selected from the group consisting of (A) metals selected from the group consisting of Mg, Ca-Al combinations, Sr-Al combinations, Ce, Ba, and mixtures thereof, and, (A) metals plus Ni. The impregnated insulation materials may also be pre-heated in air so that the oxides are formed prior to their insertion into the generator apparatus. These electrochemical cells are contacted with a hydrocarbon fuel gas and operated at over 700.degree. C. The metal oxides formed are effective in preventing cell assembly deterioration due to carbon deposition from the hydrocarbon fuel and any elemental nickel formed is effective as a fuel reforming medium.
