摘要： A fuel cell cathode flow field has multiple channels each with a cross-sectional area that varies along the length of the channel such that oxygen availability at every lengthwise position along the channel is kept substantially constant for a given channel length and air stoichiometry ratio. Each channel comprises a flat floor with substantially constant depth and a pair of side walls extending upwardly from the floor; the side walls each taper inwards from channel inlet to outlet with a convex curve relative to the channel centreline. Achieving substantially uniform oxygen availability throughout the flow field results in substantially uniform current density throughout the flow field, which is desirable for efficient fuel cell operation and improved performance.

摘要： A fuel cell plate comprises a basic plate generally adaptable to be used, for a flow of a fluid, as a cathode. The basic plate has essentially a trapezoidal top view, delimitated by a pair of longitudinal margins, and a long and short transversal margins and is provided with inlet and outlet apertures, the former being disposed parallel and close to the long transversal margin, while the latter is disposed close to the short transversal margin. The basic plate also incorporates a continuous wall, spaced from the pair of longitudinal margins and the long and short transversal margins, and extending upwardly from a top of the basic plate, the continuous wall circumscribing a flow field divided into a multiplicity of channels. Cross-sections of the flow field of the basic plate, open to the flow of fluid entering through the inlet apertures, then flowing throughout the channels and exiting through the outlet apertures, continuously diminish, so that, accordingly, velocities of the fluid continuously increase.
摘要翻译：燃料电池板包括通常适用于作为阴极的流体流动的碱性板。基本板具有基本上梯形的顶视图，其由一对纵向边缘分隔开，并且具有长而短的横向边缘，并且设置有入口和出口孔，前者平行并且靠近长的横向边缘，而后者靠近短横向边缘。基本板还包括与一对纵向边缘间隔开的连续壁和长的和短的横向边缘，并且从基板的顶部向上延伸，连续的壁围绕划分成多个通道的流场。基本板的流场的横截面对通过入口孔进入的流体的流动开放，然后流过通道并通过出口孔流出，其连续减小，使得流体的速度连续增加。

摘要： A fuel cell plate comprises a basic plate generally adaptable to be used, for a flow of a fluid, as a cathode. The basic plate has essentially a trapezoidal top view, delimitated by a pair of longitudinal margins (102), and a long and short transversal margins (104, 106) and is provided with inlet and outlet apertures, the former (126) being disposed parallel and close to the long transversal margin, while the latter (128) is disposed close to the short transversal margin. The basic plate also incorporates a continuous wall (110), spaced from the pair of longitudinal (102) margins and the long and short transversal margins (104, 106), and extending upwardly from a top of the basic plate, the continuous wall circumscribing a flow field (102) divided into a multiplicity of channels. Cross-sections of the flow field of the basic plate, open to the flow of fluid entering through the inlet apertures, then flowing throughout the channels and exiting through the outlet apertures, continuously diminish, so that, accordingly, velocities of the fluid continuously increase.

摘要： This invention relates to a foldable wheelbarrow and a foldable hand cart. Both comprise a wheel mounting assembly, a leg assembly rotatably connected to the wheel mounting assembly, one or more wheels rotatably connected to the wheel mounting assembly, a collapsible container connected to the wheel mounting and leg assemblies, and at least one support member rotatably connected to both the wheel mounting and leg assemblies and serving to maintain the wheelbarrow in an erected position. The handle members have a pair of handles and a kicker; the kicker has a pair of interconnected longitudinally-extending portions that are each rotatably connected to an associated rear handle segment thereby enabling the handle members to rotate between erected and folded position.
