  "textContent": "Embodiments of the invention relate to a membrane-electrode assembly comprising a membrane structure with an anode layer, a cathode layer, and a membrane layer, wherein the membrane layer is positioned between the anode layer and the cathode layer. The membrane-electrode assembly furthermore comprises an anode-side gas-diffusion layer arranged on the anode layer and a cathode-side gas-diffusion layer arranged on the cathode layer. Furthermore, at least one of the anode-side gas-diffusion and the cathode-side gas-diffusion layers has a structure on the side facing away from the membrane structure. According to some embodiments, the structure comprises a plurality of columns for forming a laterally-open flow field, wherein the columns have support surfaces for supporting a bipolar plate.",
