    摘要： The present invention discloses a fuel cell having at least one bi-cell. The bi-cells may be stacked in series to achieve a desired power output. Each bi-cell is a unit cell comprising two hydrogen electrodes, two air/oxygen electrodes, two electrolyte distributors and a gas diffuser. The hydrogen electrodes are disposed adjacent to one another and the air/oxygen electrodes are disposed on the outside ends of the hydrogen electrodes. An electrolyte distributor is disposed between each adjacently set hydrogen electrode and air/oxygen electrode. A gas diffuser/distributor is disposed between the hydrogen electrodes. An elastomeric material is injected between the electrodes and distributors to provide mechanical stability. Further, the entire bi-cell is overmolded with an elastomeric material. Ribs are set in the distributors to prevent the elastomeric material from flowing into areas designed for electrolyte flow, hydrogen flow and mechanical restraints and to promote uniform spacing between the various components. When the bi-cell units are stacked and secured, sufficient openings for air are formed to allow air to contact the air/oxygen electrodes.

    摘要翻译： 本发明公开了一种具有至少一个双电池的燃料电池。 双电池可以串联堆叠以实现期望的功率输出。 每个双电池是包括两个氢电极，两个空气/氧电极，两个电解液分配器和气体扩散器的晶胞。 氢电极彼此相邻配置，空气/氧电极设置在氢电极的外端。 在每个相邻设置的氢电极和空气/氧电极之间设置电解质分配器。 气体扩散器/分配器设置在氢电极之间。 在电极和分配器之间注入弹性体材料以提供机械稳定性。 此外，整个双电池被弹性体材料包覆成型。 肋条设置在分配器中，以防止弹性体材料流入设计用于电解质流动，氢气流动和机械约束的区域，并促进各种部件之间的均匀间隔。 当双电池单元堆叠并固定时，形成足够的空气开口以允许空气接触空气/氧气电极。

    摘要： An electronic device for securing the contents of data storage and processing elements. The device includes a security element and a phase-change element connected in a parallel arrangement. The security element is a three-terminal device, having an ON state and an OFF state which differ in resistance and regulate electronic access to the phase-change element by controlling the flow of electrical current applied to the parallel combination. In the ON state, the resistance of the security element is less than that of the phase-change element, thereby precluding a determination of the resistance of the phase-change element. In this PROTECT mode, the contents of the phase-change element are secured. In the OFF state, the resistance of the security element is greater than that of the phase-change material so that the resistance of the parallel combination approaches that of the phase-change element. In this READ mode, the resistance and information content of the phase-change element can be determined.
