NOVELTY - Fuel cell manifold system comprises a fuel header, an exhaust header, and a fuel cell flow path from the fuel header across a fuel cell anode (20) and to the exhaust header. The manifold system further comprises two layers having channels patterned to define the flow path.    USE - The fuel cell manifold system is used in an electrical current generating apparatus (claimed), useful in electronic devices.    ADVANTAGE - The use of patternable substrate materials for the two layers facilitates the creation of a fluid communication path including a precise fuel flow path (35) and an exhaust flow path (37).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (a) a fuel cell system comprising a fuel cell having segmented anodes, each measuring a minimal length to consume or catalyze fuel introduced to the anode;    (b) a fuel cell apparatus comprising an anode comprising two angled portions (25, 27) and a planar portion (29) extending between the angled portions, a cathode (22), and an electrolyte (24) between the anode and cathode, where the anode is of minimal length to consume or catalyze all fuel introduced to the anode;    (c) an electrical current generating apparatus comprising fuel cells, and a fuel cell manifold patterned into a substrate;    (d) a method of removing by-products from a fuel cell, which comprises flowing fuel into an arched fuel cell anode in a first direction and exhausting the by-products to an exhaust header in a second direction immediately after fuel is consumed or catalyzed;    (e) a method of making a fuel cell fluid communication path, which comprises providing two layers (31, 33), patterning a fuel path in the first layer in a first direction and in the second layer in a second direction, and patterning an exhaust path through the first and second layers; and    (f) a power generating apparatus comprising mechanism for generating an electrical current from a chemical reaction, mechanism for providing a fuel flow through a patterned substrate to the mechanism for generating an electrical current, and mechanisms for removing by-products from the fuel flow to an exhaust header patterned in a substrate.
