NOVELTY - The method for producing a reinforced rigid anode monolith and fuel, comprises adding internal reinforcement materials comprising carbon to an organic aerogel/xerogel precursor solution to form a precursor mixture, gelling the precursor mixture to form a composite gel, drying the composite gel, and pyrolyzing the composite gel to form a wettable aerogel/carbon composite or a wettable xerogel/carbon composite and the internal reinforcement materials. The composites comprise chars and the internal reinforcement materials, and have a density of 0.56 grams/cm3.    USE - The method is useful for producing a reinforced rigid anode monolith and fuel, which is obtained from carbon based materials such as biomass or agricultural clippings, sawdust, petroleum pitch, coal tar pitch, petroleum tar and pitch, peat, tar derived from tar sands and low rank coals.    ADVANTAGE - The method is capable of efficiently and rapidly producing a reinforced rigid anode monolith and fuel in improved manner.    DETAILED DESCRIPTION - The method for producing a reinforced rigid anode monolith and fuel, comprises adding internal reinforcement materials comprising carbon to an organic aerogel/xerogel precursor solution to form a precursor mixture, gelling the precursor mixture to form a composite gel, drying the composite gel, and pyrolyzing the composite gel to form a wettable aerogel/carbon composite or a wettable xerogel/carbon composite and the internal reinforcement materials. The composites comprise chars and the internal reinforcement materials, and have a density of 0.56 grams/cm3. The composite is useful as an anode with the chars, which are fuels combusted in a molten salt electrochemical fuel cell in 500-800 C to produce electrical energy. The internal reinforcement materials comprise graphite. Carbon dioxide is unable to percolate through the interior of the xerogel/carbon composite. The composite gel is dried by supercritical-critical solvent extraction, and air drying. The internal reinforcement materials are ceramic and glassy materials. The carbon materials are carbon fibers, carbon paper, carbon rods, carbon fabrics, carbon screens, graphite or highly graphitized carbon structures. An INDEPENDENT CLAIM is included for a reinforced rigid anode monolith and fuel.    DESCRIPTION OF DRAWING(S) - The diagram shows a potential contributed by the carbon anode measured against a reference electrode (gold/carbon dioxide, air) verses current density (mA/cm2).
