NOVELTY - A fuel cell layer comprises at least two unit fuel cells comprising front cavity formed between front and back process layers and in communication with a front side of a fuel cell layer, a back cavity in communication with the back side of the fuel cell layer, front and back perimeter barriers, and first frame. The front or back process layer facilitates a transport process between the reactant front plenum and the back oxidant plenum.    USE - Used as a fuel cell layer for an electrical appliance, i.e. an airplane, a car, a laser pointer, a cellular phone, a wireless phone, a projector, a television, a CD player, a radio, or a flashlight (claimed).    ADVANTAGE - The invention simplifies the overall design, reduces the number of components needed in construction, and simplifies the construction steps needed to make the device. The frame construction also increases the precision of alignment between process layers and perimeter barriers used in the unit fuel cells. The frame based design simplifies the task of sealing layers by only having to bond similar materials to each other. The fuel cell is capable of low cost manufacturing because of having fewer parts than the layered planar structure fuel cell, and has the ability to utilize a wide variety of electrolytes and reduced contact resistance within the fuel cell. It also has the ability to scale high power has long been desired, has larger reactant surface areas, is scaled to micro-dimensions, and is capable of being connected together without the need for external components for connecting the fuel cells together. Increasing the aspect ratio is beneficial for increasing the efficiency of the fuel cell.    DETAILED DESCRIPTION - A fuel cell layer with frames comprises at least two unit fuel cells (12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 31) disposed adjacent each other to form a front side and a back side (34) of the fuel cell layer; a front plenum (36) comprising a fuel communicating with the front side (32); and a back oxidant plenum comprising an oxidant communicating with the back side. The unit fuel cells comprise a front process layer; a back process layer; a front cavity formed between the front process layer and back process layer; a back cavity formed between the back process layer of the first unit fuel cell and the front process layer of the second unit fuel cell; a front perimeter barrier disposed on the back process layer surrounding the back cavity; a back perimeter barrier disposed on the front process layer substantially surrounding the front cavity; and a first frame formed from the front process layer, the front perimeter barrier, and the front cavity, or formed from the back process layer, the back perimeter barrier and the back cavity. The front cavity is in communication with the front side of the fuel cell layer, and the back cavity is in communication with the back side of the fuel cell layer, and front process layer or the back process layer facilitates a transport process between the reactant front plenum and the back oxidant plenum.
