    摘要： A fuel cell (200) includes a membrane electrode assembly (210) located together with a layer of porous, z-axis electrically conductive, non-linear positive temperature coefficient (NPTC) material (250). The NPTC material (250) operates to selectively limit the amount of electrons collected from localized areas of the membrane electrode assembly (210) in order to reduce hot spots.

    摘要： A very thin fuel cell (500) is formed by stacking a plurality of membrane electrode assemblies (MEA) (210) and a plurality of double sided distribution plates (220). The distribution plates serve to distribute fuel and oxidant to the MEAs, and they are electrically and thermally conductive and gas impermeable, and have fuel and oxidant distribution channels formed on opposite sides. The oxidant flowing through the oxidant distribution channels also provides thermal management to the fuel cell, eliminating the need for a separate heat exchange system. The MEAs and the distribution plates are arranged in an alternating stack (200) such that the fuel distribution channel side (315) is in intimate and direct contact with the MEA anode (212), and such that the oxidant distribution channel (415) is in intimate and direct contact with the MEA cathode (214). The distribution plate acts as a bipolar plate and also as a heat exchanger.

    摘要： A fuel cell (30) has an internal fuel source (35) that is in a matrix around a membrane electrode assembly (29). The membrane electrode assembly is constructed to be generally formed in the shape of a solid cylinder. The fuel cell has a porous central core (22) of reticulated vitreous metal that is formed in the shape of a solid cylinder. The porous central core serves to distribute oxidant throughout the fuel cell. A cathode (23) is situated coaxially around the porous central core, and has a catalytic layer on the outer side. A solid polymer electrolyte (25) is situated coaxially around the cathode and in intimate contact with the catalytic layer. An anode (27) is situated coaxially around the electrolyte, and a second layer of catalytic material is situated between the electrolyte and the anode. A housing (31) contains the internal fuel supply and holds the membrane electrode assemblies in place.

    摘要： An optical switch assembly for a two-way radio has electrical and mechanical subassemblies. The electrical portion consists an IR emitter (12) and a pair of IR receivers (14,16) strategically positioned upon a printed circuit board (10). The mechanical portion consists of a rotatable interposer mechanism (20) interconnected to a knob (35) on the radio via a shaft (28). The interposer has inner (22) and outer (24) concentric cylindrical walls. The outer wall controls the light transmitted between the emitter and one of the receivers (16), ultimately controlling the On-Off state of the radio. The inner wall has an integrated gray-scale graphic which controls the transmission of light between the emitter and the other IR receiver (14), ultimately controlling the audio output of the radio.
