Disclosed herein is a fuel cell assembly that arranges a plurality of individual fuel cells into an array. The fuel cells are set into openings formed in a frame. The openings are arranged into the array, such as in columns and rows. A rear cover is sealingly attached to the frame, thereby defining a chamber between the frame and a base of the rear cover, where the chamber serves as a manifold. Optional supports extend from the base to the fuel cells. The void forms a fluid manifold for dispersing fuel for the fuel cells from a fuel reservoir to the fuel cells. Alternatively, the rear cover separates the interstitial space between the rear cover and the frame into compartments, which are fluidly interconnected by channels. The array may also include a functional element electrically connected to the fuel cells configured to transfer power an electronic device.

Method for preparing a magneto optic memory comprising on a support (22), such as one made of glass, metal or a plastic material, a planar sensitive film (21) of magneto optic material for receiving at each point the recording of one of the two binary digits 0 and 1 in the form of small domains juxtaposed and magnetized perpendicular to the plane of the film in one of the two possible directions with respect to the latter, the sensitive film (21) being deposited by a cathodic or other evporation process of a magentic oxide selected from the group including spinel ferrites, hexaferrites and ferrimagnetic garnets, the preceding deposition being followed by a crystallization of the amorphous regions of said film with the aid of an annealing, wherein at least one reflective film (28) and/or one film constituting a thermal screen is inserted between the support (22) and the sensitive film (21) and wherein the annealing is a fast annealing, namely of a few seconds at a temperature of between 600.degree. C. and 650.degree. C.
