    摘要： A method and apparatus are provided for humidifying oxidant supplied to a fuel cell system, which can be a single fuel cell or a multiplicity of fuel cells. A catalytic reactor is provided, which is supplied with a portion of the fuel and the oxidant. The oxidant is supplied in excess of the fuel to the reactor, so as to generate a stream of oxidant which is both heated and humidified. For an air breathing stack, this heated oxidant can simply be mixed with air flowing through the fuel cell stack. For a closed system, a heated and humidified oxidant flow, and optionally a fuel flow are mixed with additional flows of these gases supplied to the fuel cell.

    摘要： A fuel cell has a proton exchange membrane. In known manner, the fuel cell includes inlets and outlets for flow of an oxidant and for flow of a fuel gas, commonly hydrogen. To deal with the issue of humidification, the invention provides a recirculation conduit including a pump connected between the anode inlet and the anode outlet. A water separator is provided in the recirculation conduit, for separating water from fuel gas exiting the anode. A main fuel inlet is connected to the recirculation conduit, for supply of fuel. A branch conduit can be provided, to enable purge cycles and other options to be provided.

    摘要： Aspects of some embodiments of the present invention provide flow field plates that have been designed to potentially reduce the unit cost of each flow field plate employed in an electrochemical cell stack. Thus, for some embodiments of the present invention an electrochemical cell includes a number of flow field plates each having a number of manifold apertures that all have the same area. A first one of the manifold apertures is used for a first process gas/fluid and a second one of the manifold apertures is used for a second process gas/fluid. The manifold apertures on the flow field plates align to form elongate channels that extend through the electrochemical cell as described in more detail herein.

    摘要： In a fuel cell, a humidification cell stack is provided at each end of the fuel cell as an extension of the fuel cell. The cells of each of the two humidification cell stacks can be structurally similar to and can include the same membrane as the individual cells of the fuel cell stack. Flows of fuel and oxygen are then arranged to pass through each of the two humidification cell stacks for exchange of moisture. Preferably, the humidification section at one end of the fuel cell stack provides moisture exchange between incoming fuel and discharged oxygen, while the humidification section at the other end of the fuel cell stack, provides moisture exchange between the incoming oxygen and the discharged fuel. This arrangement is expected to enhance uniform operating conditions within the fuel cell stack itself, so as to ensure optimum operating conditions throughout the fuel cell stack.

    摘要翻译： 在燃料电池中，作为燃料电池的延伸部，在燃料电池的各端设置加湿电池堆。 两个加湿电池组中的每一个的电池可以在结构上类似于并且可以包括与燃料电池堆的各个电池相同的膜。 然后将燃料和氧气的流动布置成通过两个加湿电池堆中的每一个以交换水分。 优选地，燃料电池堆一端的加湿部分在燃料电池堆的另一端的加湿部分提供进入的燃料和排放的氧气之间的湿气交换，从而在进入的氧气和排出的燃料之间提供湿气交换。 期望这种布置可以增强燃料电池堆本身内的均匀操作条件，从而确保贯穿整个燃料电池堆的最佳操作条件。
