Abstract

The present application discloses a membrane-electrode assembly having an increased active area, improved fluid control capability, and reduced gas transport resistance due to electrodes having a patterned structure on both sides. A method of manufacturing the membrane-electrode assembly and a fuel cell including the membrane-electrode assembly are also disclosed. The membrane-electrode assembly according to the present invention comprises: a first electrode; a second electrode; and a polymer electrolyte membrane between the first electrode and the second electrode, in which the first electrode has a first surface facing the polymer electrolyte membrane and a second surface opposite the first surface, the first surface has a first patterned structure, and the second surface has a second patterned structure.

Description

technical field [0001] The present disclosure relates to a membrane-electrode assembly, a method of making the membrane-electrode assembly, and a fuel cell including the membrane-electrode assembly, and more particularly, to a membrane-electrode assembly having an increased active area, improved Membrane-electrode assembly with improved fluid control capability and reduced gas transport resistance, method of making the membrane-electrode, and fuel cell including the membrane-electrode assembly. Background technique [0002] Polymer Electrolyte Membrane Fuel Cells (PEMFCs) are constructed to use the structure of each stack of unit cells including a membrane-electrode assembly (MEA) and a separator (also known as a bipolar plate) to generate electricity due to its high energy efficiency and environmentally friendly features , so it has attracted attention as a next-generation energy that can replace fossil fuels. [0003] A membrane-electrode assembly typically includes an an...
