A fuel cell system having subsystems connected in series. A system includes a fuel cell engine, a plurality of switching devices, and a controller. The fuel cell engine includes a plurality of fuel cell modules connected in series as fuel cell strings, and then a plurality of these strings are connected in parallel. The switching device (s) are electrically coupled to bypass each module (s) and/or to disconnect each string (s) when desired. The decision of whether the module (s) and/or string (s) are bypassed, disconnected or held in operation is based on sensory feedback input to a finite state machine embedded within the fuel cell controller and in a fault management process. The bypass scheme at the module stage is handled in such a way that the remaining modules within the series string can provide continuous, uninterrupted current flow to the terminal application.

    具有串联连接的子系统的燃料电池系统。一种系统包括燃料电池发动机、多个开关器件和控制器。燃料电池发动机包括作为燃料电池串被串联连接的多个燃料电池模块,并且然后多个这些串被并联连接。(一个或多个)开关器件电耦合,以在需要时绕过每(一个或多个)模块和/或断连每(一个或多个)串。(一个或多个)模块和/或(一个或多个)串是被绕过、断连还是保持操作的决策是基于输入到嵌入在燃料电池控制器内的有限状态机和故障管理过程中的传感反馈。在模块级的旁路方案以使得串联串内的剩余模块可以向终端应用提供持续不中断的电流流动这样的方式处理。
