摘要： A system and method for monitoring cell voltages for a plurality of electrochemical cells connected in series forming a cell stack. The method includes dividing the cells into at least two cell groups, measuring the voltage across each cell group and estimating the minimum cell voltage for each group based on the average cell stack voltage and an estimated number of deficient cells in each group. The lowest minimum cell voltage for the entire cell stack is then determined.

摘要： A fuel cell power system has a plurality of fuel cell power modules, each module including a fuel cell and associated peripheral devices. Each fuel cell power module is controlled by its own local controller. A master controller controls each of the local controllers in accordance with overall system requirements. Optionally, a bypass allows the master controller to shut down and bypass a particular fuel cell power module, providing this system with greater flexibility, robustness and reliability. The modular system architecture also simplifies manufacturing, maintenance and repair.

摘要： A fuel cell system has: a fuel cell having a first reactant inlet, a first reactant outlet, a second reactant inlet, a second reactant outlet, and optionally a coolant inlet and coolant outlet. A first reactant supply subsystem supplies a first reactant incoming stream to the first reactant inlet of the fuel cell. A second reactant supply subsystem supplies a second reactant incoming stream to the second reactant inlet of the fuel cell. A first reactant recirculation subsystem recirculates at least a portion of the first reactant exhaust stream from the first reactant outlet to an enthalpy shifting subsystem in which one portion of the heat and moisture in first reactant exhaust stream is transferred to one of the first reactant incoming stream in the first reactant supply subsystem and the second reactant incoming stream in the second reactant supply subsystem. Another portion of the heat and moisture is transferred to the other stream. A method of controlling reactant and water in a fuel cell system is also disclosed.

摘要： When a conventional fuel cell module is shutdown the conditions within the fuel cell stack change. The conditions change because elements that support and regulate the operation of the fuel cell stack switch to their respective shutdown states. For example, the input and output valves are closed, which cuts off the supply inflows and exhaust outflows. Moreover, when an element such as a flow control device switches to a shutdown state internal conditions, such as for example, the pressure within the anode electrodes change. When the internal conditions of the fuel cell stack change the reactants (e.g. hydrogen and oxygen) remaining in the fuel cell stack and the feed lines (between the fuel cell stack and the closed valves) are substantially consumed in combustion reactions as opposed to being consumed in electrochemical reactions yielding a useful form of energy.
摘要翻译：当常规燃料电池模块关闭时，燃料电池堆内的状况发生变化。条件改变是因为支持和调节燃料电池堆的操作的元件切换到它们各自的关闭状态。例如，输入和输出阀是关闭的，其切断供给流入和排出流出。此外，当诸如流量控制装置的元件切换到关闭状态时，例如，阳极内的压力变化。当燃料电池堆的内部条件改变燃料电池堆中剩余的反应物（例如氢和氧）和燃料反应中的进料管线（燃料电池堆与封闭阀之间）的消耗相对于消耗在电化学反应中产生有用的能量形式。
