Proton exchange membrane fuel cell (PEMFC) is a clean and efficient green environmental protection power supply with broad application prospects. Membrane electrode assembly is the core component of PEMFC which directly affects the performance and commercialization of PEMFC. In this paper

the global patents in the field of membrane electrode assembly were taken as the research objects. The trend of patent application

the technical development trend and technical effect were analyzed by using patent and text analysis methods. The layout

technical characteristics

competitive advantages and technological trends of the main institutions in China and abroad were identified. Finally

this paper put forward some suggestions

such as attaching importance to the patent protection strategy

accelerating the research and development of key technologies

and effectively linking production

education and research.
