摘要： A passage structure for PEM fuel cells is configured locally differently in order to adapt the flow of gas on the membrane electrode assembly (MEA). Starting from the cathode entry port, the active gas volumetric flow per unit area on the MEA is locally varied by changing the number and/or cross section of the gas-carrying passages, so that the flow decreases toward the cathode exit port. Suitable configuration of the passage structure according to the invention allows the steam partial pressure to be optimally matched to the local conditions. The mass conversion is improved in these regions as a result without the electrolyte's drying out. At locations in the flowfield with a low gas humidity, the measures according to the invention (increased number of passages or passage width) significantly reduce the flow velocity. As a result, the transfer of water from the MEA to the gas flow is reduced and drying of the MEA is diminished.
摘要翻译：用于PEM燃料电池的通道结构被局部地配置以便适应膜电极组件（MEA）上的气体流。从阴极入口开始，MEA上每单位面积的活性气体体积流量通过改变气体输送通道的数量和/或横截面而局部变化，使得流向阴极出口减少。根据本发明的通道结构的合适构造允许蒸汽分压与局部条件最佳地匹配。结果，在这些区域中质量转化率得到改善，没有电解质干燥。在具有低气体湿度的流场中的位置处，根据本发明的措施（增加的通道数或通道宽度）显着降低了流速。结果，水从MEA向气流的转移减少，MEA的干燥减弱。

摘要： A method for operating a fuel cell stack (10) for a fuel cell system, in particular of a vehicle, in which by reversing the flow direction (14, 16) of a coolant during a cooling operation, the coolant in the fuel cell stack (10) is initially conveyed in a first direction (14). The coolant is subsequently conveyed in a second direction (16) which is at least substantially opposite to the first direction (14). A time period, after the elapse of which the flow direction (14, 16) is reversed, is changed during the cooling operation. In addition, a distance at which a coolant volume is situated from a heat source (12) that is present in the fuel cell stack (10) may be changed during the cooling operation. The invention further relates to a fuel cell system.

摘要： A method for the operation of a computer system controlled by a real-time operating system, which computer system processes interrupt signals. Upon the occurrence of an interrupt signal, the computer system interrupts a program that is to be processed at that time. The acceptance of further interrupt signals is blocked, and an interrupt routine belonging to this interrupt signal is called. During the processing of this interrupt routine, a first part of the program parameters of the program that is interrupted upon the occurrence of the interrupt signal is intermediately stored, and at least one datum concerning the interrupt signal is stored in an interrupt memory. A branching takes place from the interrupt routine to an interrupt management routine (IVR), whereby the acceptance of further interrupt signals is again cleared during the processing of the IVR. During the processing of the IVR, the datum belonging to the interrupt signal is erased; the remaining part of the program parameters of the program that is interrupted upon the occurrence of the interrupt signal is intermediately stored. Dependent on the datum concerning the interrupt signal, at least one reaction routine belonging to this interrupt signal is activated. After the processing of the IVR, the operating system branches back to the program that was interrupted upon the occurrence of the interrupt signal, using the intermediately stored program parameters.
