Electrochemical gas sensor

The invention relates to an electrochemical gas sensor (1) comprising a stack of at least one first electrode (3) and a second electrode (6), each of which is arranged on a carrier membrane (2, 5), and a separator (4) arranged between the electrodes (3, 6), the electrochemical gas sensor has a gas guide path (14) between the first electrode (3) and the second electrode (6). The gas guide path (14) is formed inside a structural space defined by the electrodes (3, 6). 本发明涉及一种电化学的气体传感器(1)，其具有至少一个第一电极(3)和第二电极(6)的堆叠组件和设置在电极(3、6)之间的分离器(4)，所述第一电极和第二电极分别设置在一个载体膜片(2、5)上，电化学的气体传感器在所述第一电极(3)与所述第二电极(6)之间具有导气路径(14)。所述导气路径(14)构成在通过电极(3、6)限定的结构空间内部。
