摘要： The invention is directed to a piping structure of a fuel cell stack that discharges gas from a coolant fluid outlet pipe before the gas accumulates in a coolant fluid passage within the fuel cell stack. In addition, the piping structure drains fluid from a fuel gas outlet pipe and an oxidant gas outlet pipe before the fluid accumulates in a fuel gas passage and an oxidant gas passage, respectively, within the fuel cell stack. In this way, the piping structure described herein improves cooling performance of the coolant fluid as well as power generation performance and life of the fuel cell stack.

摘要： Methods and systems are provided for cold-start of fuel cell stack in fuel cell vehicles. In one example, a method may include in response to cold-start of fuel cell vehicle, limiting the load drawn from the fuel cell stack. In addition, a coolant pump may be operated at a higher rate through a bypass loop to get heat quickly to the fuel cell stack to increase the solubility of water in the fuel cell stack to prevent ice formation. The net effect is that the fuel cell stack is then operated within the ice capacity of the membrane, and start-up at lower temperatures is possible without experiencing an intermittent performance drop due to active area freezing. Once the fuel cell stack is sufficiently warmed up, the coolant pump rate and fuel cell stack may be adjusted according to the demand.
摘要翻译：提供了用于燃料电池车辆中燃料电池堆的冷起动的方法和系统。在一个示例中，方法可以包括响应于燃料电池车辆的冷启动，限制从燃料电池堆提取的负载。此外，可以通过旁路回路以更高的速率操作冷却剂泵，以便快速地将热量加热到燃料电池堆，以增加水在燃料电池堆中的溶解度以防止形成冰。净效应是燃料电池堆在膜的冰容量内运行，并且在较低温度下启动是可能的，而不会由于活动区域冻结而经历间歇性的性能下降。一旦燃料电池堆被充分预热，可以根据需要调节冷却剂泵速率和燃料电池堆。

摘要： Methods are disclosed for starting up a fuel cell system from starting temperatures below 0 °C. The methods apply to systems comprising a solid polymer electrolyte fuel cell stack whose cathodes comprise an oxygen reduction reaction (ORR) catalyst and whose anodes comprise both a hydrogen oxidation reaction (HOR) catalyst and an oxidation evolution reaction (OER) catalyst. In the methods, from the beginning of starting up until the fuel cell temperature reaches 0 °C, the fuel cell stack current is kept sufficiently low such that the current density drawn does not exceed the stack's capability for the oxidation evolution and the oxygen reduction reactions to occur at the anode and cathode respectively (i.e. current density drawn is less than the stack's maximum OER/ORR current density).

摘要： [Problem] To provide a fuel-cell-stack manufacturing method capable of increasing the load that a raised piece of a deformation absorption member can receive from the separator unit. [Solution] The deformation absorption member 20 used in the fuel-cell-stack 1 manufacturing method is disposed between an anode side separator 11 and a cathode side separator 12, and comprises a thin-board-like base material 21, and a plurality of raised pieces 22 that are provided raised from one surface 21a of the base material in a grid pattern. In the arrangement step, an extension portion (the free end portion 22b) extended from the proximal end (the fixed end portion 22a) of the raised piece provided on one surface of the base material is disposed so as to be abutted to the cathode side separator or the anode side separator. The setting step sets the interval between the anode side separator and the cathode side separator along the lamination direction X so that the deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end that is moved due to the deformation will not come in contact with the cathode side separator or the anode side separator.
