NOVELTY - A nanostructured carbon electrode is fabricated by providing carbon material of large-effective-surface-area polyaromatic hydrocarbon (LPAH) (140), mixing carbon material of LPAH with surfactant in solution to form suspension, depositing suspension on substrate to form layered structure, and sintering layered structure.    USE - Fabrication of nanostructured carbon electrode for electrochemical devices, such as solar cells, batteries capacitors, and fuel cells.    ADVANTAGE - Fabrication process is simple. LPAH layers increase diffusion of charge species and catalytic reactions.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) fabrication of nanostructured carbon electrode which involves providing patterned graphite film substrate, depositing suspension of large-effective-surface-area polyaromatic hydrocarbon (LPAH) (140) on patterned graphite substrate, sealing edges of patterned graphite substrate with deposited suspension of LPAH with polyimide film to form layered structure, and curing layered structure;    (2) article of manufacture comprising substrate with 1st surface and 2nd opposing surface, dye-coated titanium dioxide (TiO2) nanoparticle (NP) film (120) formed on 1st surface or 2nd surface of substrate, graphite film (150) with 1st surface and 2nd opposing surface, LPAH film formed on 1st surface or 2nd surface of graphite film, and layer of electrolyte (130) positioned between and in contact with LPAH film and dye-coated TiO2 NP film in which substrate and graphite film are separated apart from dye-coated TiO2 NP film, layer of electrolyte, and LPAH film; and    (3) article of manufacture comprising anode, cathode comparing a graphite film and a film of LPAH formed on graphite film in which anode and cathode are positioned apart such that LPAH film faces anode to define a space between LPAH film and anode, and electrolyte filled in the space defined between LPAH film and anode.
