摘要： A system and method for increasing the temperature of a fuel cell stack quickly, especially at cold stack start-up. The method includes determining whether the fuel cell stack is below a first predetermined temperature threshold, and, if so, starting a cooling fluid flow through the stack and engaging a shorting circuit across the stack to short circuit the stack and cause the stack to operate inefficiently. The method then determines a desired heating rate of the fuel cell stack and calculates a cathode airflow to the fuel cell stack based on the desired heating rate. The method reduces the flow of cathode air to the stack if a minimum cell voltage is below a predetermined minimum cell voltage threshold and disengages the shorting circuit and applies vehicle loads to the stack when the stack temperature reaches a predetermined second temperature threshold.
摘要翻译：一种用于快速提高燃料电池堆的温度的系统和方法，特别是在冷堆启动时。该方法包括确定燃料电池堆是否低于第一预定温度阈值，并且如果是，则启动冷却流体流过堆叠并且跨越堆叠接合短路电路以使堆叠短路并且使得堆栈无效地运行。该方法然后确定燃料电池堆的期望加热速率，并基于期望的加热速率计算到燃料电池堆的阴极气流。如果最小电池电压低于预定的最小电池电压阈值，则该方法减少阴极空气流到堆叠的流量，并且当堆叠温度达到预定的第二温度阈值时，将短路电路解除并将车辆负载施加到堆叠。

摘要： Processes to shut down a fuel cell system are described. In one implementation (300), a load (215) is cyclically engaged and disengaged across a fuel cell stack (205) so as to deplete the fuel available to the system's fuel cells (205). Voltage and/or current thresholds may be used to determine when to engage and disengage the load (215) and when to terminate the shutdown operation. In another implementation (500), a variable load (405) is engaged and adjusted so as to deplete the fuel available to the system's fuel cells (205). As before, voltage and/or current thresholds may be used to determine when to adjust the load (405) and when to terminate the shutdown process. In still another implementation, a load (215 or 405) may be periodically engaged and disengaged during some portion of the shutdown process and engaged but adjusted during other portions of the shutdown process.
