NOVELTY - A fuel cell for generating electrical energy, comprises set of cells arranged on at least one chassis (106, 108), and each cell (104) including anode structure (110), cathode structure (112), and electrolyte; hydrogen distribution channel configured to deliver hydrogen to anode structures in the set of cells; and oxygen distribution channel configured to deliver oxygen to the cathode structures in the set of cells.    USE - The fuel cell is for generating electrical energy used in a portable electronics device e.g. cell phone (claimed) and laptops.    ADVANTAGE - The fuel cell has reduced cell size and improved power density. The fuel cell provides a power density greater than 20 (preferably greater than 100) Watts/cm3.    DETAILED DESCRIPTION - A fuel cell for generating electrical energy, comprises:    (1) a set of cells arranged on at least one chassis, and each including an anode structure that extends from the at least one chassis and supports a hydrogen catalyst; a cathode structure that extends from the at least one chassis and supports a cathode catalyst; and an electrolyte disposed to electrically isolate the anode structure from the cathode structure and permit passage of ions between the anode structure and the cathode structure;    (2) a hydrogen distribution channel configured to deliver hydrogen to the anode structures in the set of cells; and    (3) an oxygen distribution channel configured to deliver oxygen to the cathode structures in the set of cells.    An INDEPENDENT CLAIM is also included for a method of fabricating a fuel cell, comprising:    (1) forming a set of set of anode structures that each extend from at least one planar chassis and a set of set of cathode structures that each extend from the at least one planar chassis;    (2) forming electrical connectivity with the set of anode structures and the set of cathode structures;    (3) depositing an anode catalyst onto surfaces of the set of anode structures;    (4) depositing a cathode catalyst onto surfaces of the set of cathode structures; and    (5) depositing an electrolyte at least partially between the set of anode structures and the set of cathode structures.
