    Abstract: A bipolar separator plate for fuel cells consists of a molded mixture of a vinyl ester resin and graphite powder. The plate serves as a current collector and may contain fluid flow fields for the distribution of reactant gases. The material is inexpensive, electrically conductive, lightweight, strong, corrosion resistant, easily mass produced, and relatively impermeable to hydrogen gas. The addition of certain fiber reinforcements and other additives can improve the properties of the composite material without significantly increasing its overall cost.

    Abstract: A unit cell is composed of a pair of electrodes with a catalyst layer, a polymer electrolyte film interposed between the pair of electrodes, a separator having means for supplying hydrogen-containing gas to one of the electrodes, and a separator having means for supplying oxidizing gas to the other electrodes. A plurality of such cells are stacked with sealant applied to at least part of the peripheries of the electrodes so as to form a polymer electrolyte fuel cell. This polymer electrolyte fuel cell is superior in durability and productivity. For high reliability, a gasket sealant, the sealant for cooling water, and the sealant for water or the gas in an internal humidifier can be formed of a polymer compound having a main chain skeleton of polyisobutylene.

    Abstract: Improved fuel cell stacks (1) constructed from a plurality of cells, each comprising a series of interrelated mono and bipolar collector plates (BSPs), which in turn are built up by lamination of a core of related non-conductive plastic or ceramic platelets (12) sandwiched between conductive microscreen platelets of metal or conductive ceramic or plastic with an electrode membrane (EMA) (5 A, B, C, D) between adjacent BSPs. The platelets, both metal and plastic of the composite BSPs, are produced from sheet material with through and depth features (18, 17) formed by etching, pressing, stamping, casting, embossing and the like. Adjacent plates each with correspondingly relieved features form serpentine channels within the resultant monolithic platelet/cell stack for integrated fluid and thermal management. The plastic platelets are particularly useful for PEM fuel cells employing H2 and Air/O2 as fuel. The platelets are easily made by printing (embossing) processes, and dies made by photolithographic etching for rapid redesign. Each BSP can be individually tailored to each type of membrane, fuel, and intra-cell location within the stack (1). As materials are cheap and easy to manufacture and assemble, lightweight fuel cells of very high power density are realizable. Industrial applicability includes both stationary and vehicular power supplies, in both micro and macro sizes.

    Abstract translation: 改进的由多个单元构成的燃料电池堆(1),每个单元包括一系列相互关联的单相和双极集电板(BSP),其又通过层叠相关的非导电塑料或陶瓷片晶的核心( 12)夹在相邻BSP之间的金属或导电陶瓷或塑料的导电微孔板与电极膜(EMA)(5A,B,C,D)之间。 复合BSP的金属和塑料的片晶由片材制成,其具有通过蚀刻,压制,冲压,铸造,压花等形成的贯穿和深度特征(18,17)。 相邻的板各自具有相应的减轻特征,在所得到的整体式血小板/细胞堆中形成蛇形通道,用于集成的流体和热管理。 塑料小片对于使用H 2和空气/ O 2作为燃料的PEM燃料电池特别有用。 通过印刷(压花)工艺和通过光刻蚀刻制成的模具可以容易地制备血小板,以便快速重新设计。 每个BSP可以针对堆叠(1)内的每种类型的膜,燃料和单元内位置单独地定制。 由于材料便宜且易于制造和组装,因此具有非常高功率密度的轻质燃料电池是可实现的。 工业应用包括微型和微型尺寸的固定和车载电源。
