电池组末端电池加热器控制方法
摘要：
一种燃料电池系统，其在燃料电池系统中的燃料电池组的末端电池中使用末端电池加热器，其始终保持末端电池的温度高于电池组的工作温度，以减少末端电池中的水。在一个实施方案中，贯穿燃料电池组的整个输出功率范围，末端电池的温度保持在80℃-85℃的范围内。根据本发明另一个实施方案，末端电池是电耦合串联的，并且选择用于控制末端电池加热器的控制信号以将最热的末端电池加热到期望温度。
摘要（英）：

A fuel cell system that employs end cell heaters in the end cells of a fuel cell stack in the fuel cell system that consistently maintain the temperature of the end cells above the operating temperature of the stack so as to reduce water in the end cells. In one embodiment, the temperature of the end cells is maintained within the range of 80 DEG C.-85 DEG C. across the entire output power range of the fuel cell stack. In accordance with another embodiment of the invention, the end cells are electrically coupled in series, and the control signal for controlling the end cells heaters is selected to heat the warmest end cell to the desired temperature.
