Membrankammern

Membrankammern, often translated as membrane chambers or membrane cells, are specialized structures found in certain biological and electrochemical systems. In biology, they can refer to compartments within cells where specific membrane-bound processes occur, such as the thylakoid membranes within chloroplasts where photosynthesis takes place, or the cristae within mitochondria where cellular respiration is facilitated. These chambers are defined by their surrounding lipid bilayers, which create distinct chemical environments and allow for the spatial organization of enzyme complexes and reaction pathways.

In an electrochemical context, a membrankammer refers to a component of an electrolytic cell or a fuel cell. This chamber houses the ion-exchange membrane, which serves as a barrier between the anode and cathode compartments. The membrane's role is crucial as it selectively allows the passage of specific ions while preventing the direct mixing of reactants or products. This selective permeability is essential for the efficient operation of these electrochemical devices, ensuring the desired chemical reactions proceed and electricity is generated or consumed. The design of the membrankammer influences factors such as mass transport, current distribution, and overall cell performance.
