The Proton Exchange Membrane Fuel Cell (PEMFC) offers an environmentally friendly solution for power generation and is increasingly becoming a key force in accelerating the achievement of sustainable development goals. This paper constructs a dataset of patents and papers in the field of the proton exchange membrane fuel cell, applies the Bertopic model in natural language processing for topic identification, and calculates the core technology scores for each topic based on importance, innovation, and high competitive barriers, identifying the key core technology topics in this field, which provides guidance and reference for related research and practice. The results of the study show that the patent documents and academic papers show obvious differentiation in technical topics: the TOP3 key core technologies identified in the patent text include “Battery Separator Materials”, “Rubber Seal Materials” and “Porous Carbon Fiber Materials”; the TOP3 key core technologies identified in the paper text include “Palladium-based Electrocatalysts”, “Graphene Oxide Composite Membrane” and “Platinum-graphene Oxide Catalysts”.

摘要

The Proton Exchange Membrane Fuel Cell (PEMFC) offers an environmentally friendly solution for power generation and is increasingly becoming a key force in accelerating the achievement of sustainable development goals. This paper constructs a dataset of patents and papers in the field of the proton exchange membrane fuel cell, applies the Bertopic model in natural language processing for topic identification, and calculates the core technology scores for each topic based on importance, innovation, and high competitive barriers, identifying the key core technology topics in this field, which provides guidance and reference for related research and practice. The results of the study show that the patent documents and academic papers show obvious differentiation in technical topics: the TOP3 key core technologies identified in the patent text include “Battery Separator Materials”, “Rubber Seal Materials” and “Porous Carbon Fiber Materials”; the TOP3 key core technologies identified in the paper text include “Palladium-based Electrocatalysts”, “Graphene Oxide Composite Membrane” and “Platinum-graphene Oxide Catalysts”.
