摘要： The present invention describes an electrochemical system as well as a bipolar plate for use in an electrochemical system. The electrochemical system (1), consists of a layering of several cells (2), which in each case are separated from one another by bipolar plates (3), wherein the bipolar plates comprise openings for the cooling (4) or for the removal and supply of operating media (5) to the cells, and the layering may be set under mechanical compressive stress, wherein at least one cell comprises an electrochemically active region (6) which is surrounded by a boundary wall (7) of the bipolar plate, and a channel structure (8) of the bipolar plate is provided within the electrochemically active region, for the uniform media distribution, wherein at least one gas diffusion layer (9) is provided for the micro-distribution of media. Limitation elements (10) are provided in the border region between the channel structure as well as the boundary wall, for avoiding fluid from bypassing between the channel structure and the boundary wall, wherein the gas diffusion layer covers the channel structure and/or at least parts of the limitation elements. The reliability and the efficiency of electrochemical systems are decisively increased by way of preventing the bypass in the border region of the electrochemically active field.
