摘要： A defective operation of a valve (15, 35, 37, 39) in a drainage line (13, 21, 31, 33) of a fuel cell results in unintentionally permitting process gas to flow into the surrounding area of the fuel cells. In order to resolve this problem, the invention provides a method for monitoring the discharge of media out of a fuel cell and provides a fuel cell system, with which the gas and water stream flowing through the drainage line (25, 41) is monitored (65) by means of a Venturi nozzle (23, 40) that is connected to a differential pressure sensor (27, 53). The magnitude (67) and the temporal progression (69) of the differential pressure indicated by the differential pressure sensor (27, 53) establishes the basis for controlling the valve (15, 35, 37, 39) in the drainage line (13, 21, 31, 33) and for shutting down (71) the fuel cell block (1) in the event that the valve (15, 35, 37, 39) is defective.
摘要翻译：在一个引流管线（13,21,31,33），其结果是气体的意外操作可以在燃料电池的附近流动的燃料电池的阀（15,35,37,39）中的缺陷。为了解决这个问题，本发明提出了一种用于在其中通过在与气体和水的流动的一个差压压力传感器（27,53）相结合的文丘里管（23,40）的装置（通过漏极线从燃料电池和以前的燃料电池系统，监控媒体出口的方法被监测25,41）（65）。的尺寸（67）和压差传感器（27,53）的时间过程（69）中显示的压差形成用于在引流管线上的阀（15,35,37,39）的调节的基础（13,21,31,33 ）和（a在所述阀（15,35,37,39）的故障的情况下燃料电池块（1）的关闭71）。

摘要： The invention relates to a planar, rectangular and water-cooled fuel cell (2 1) comprising a cooling element (1, 23) with a cooling chamber (3) through whic h cooling water flows during the operation of the fuel cell (21). Cooling wate r does not flow through said cooling chamber (3) in a homogeneous manner, normally resulting in local heating of said fuel cell (21) in regions throug h which the cooling water flows through less frequently. The aim of the invention is to solve said problem by producing a fuel cell (21) which is provided with a cooling element (1, 23) which comprises an essentially rectangular cooling chamber (3) with four corner regions, whereby the openin g of a coolant flow (7a, 29a) is arranged in the first corner (5a), the openin g of a first coolant flow (7b, 29b) is arranged in a second corner (5b) and a second coolant flow (7c, 29c) is disposed in a third corner (5c). The first coolant flow (7b, 29b) has a cross section Q1 on the narrowest point thereof and the second coolant flow (7c, 29c) has a cross section Q2 on the narrowes t point thereof, the ratio of Q1/Q2 being 7 - 25.
