| Summary/Abstract |
Transport sector causes enormous carbon emissions but is struggling to reduce it in China. Hydrogen fuel cell vehicles, making it possible for zero-carbon transportation with the background of renewable energy hydrogen production in the future, are of great help to achieve the grand carbon neutrality. However, HFCVs fail to enter millions of thousands of households. To promote their application efficiently, an obstacle system with 14 factors is established based on literature review and expert consultation according to characteristics of China firstly, namely economic, technical, social and political obstacles. Interactions among the 14 obstacles are further evaluated by expert opinions. Considering uncertainty and randomness existing in subjective judgment, Cloud model is introduced to improve original DEMATEL method for the first time to analyze comprehensive importance and causal relationship. According to key parameters of the results, incomplete supporting facilities, hydrogen fuel safety issues and insufficient number of manufacturers occupy the top three importance degree. Additionally, political and technical obstacles have more obvious effects on the whole system. The results have a guiding role for both governmental regulations and enterprise practices in dealing with the obstacles. Finally, a series of general suggestions and specific policy implications for China are provided to boost prosperity.

| Summary/Abstract |
Hydrogen fuel cell vehicle is one of the important modalities of the next generation of new energy vehicles. As the basic infrastructure of hydrogen fuel cell vehicles, hydrogen refueling stations (HRSs) have drawn attention from all social circles. However, hindered by various barriers, the development of HRSs is much slower than the Chinese government's expectation. Hence, this study aims to explore critical barriers of the HRS development in China based on a modified fuzzy decision-making trial and evaluation laboratory (DEMATEL) method. Firstly, a barrier list is identified through a literature survey and expert consultation, which consists of four categories (economic, technological, social and political-regulatory aspect) and 12 potential barriers. Later, considering the subjectivity of threshold setting in the traditional fuzzy DEMATEL method, the K-means clustering algorithm is utilized to optimize the threshold value, and thus a modified fuzzy DEMATEL approach is proposed to investigate the prominence of these barriers and the cause-effect relationships among them. The results show that six barriers are regarded as key barriers to China's HRS development, and corresponding policy measures are formulated to mitigate or eliminate these critical barriers.
