Further improvements and development of new polymer electrolyte materials are required to achieve the target values stated in NEDO (New Energy and Industrial Technology Development Organization) roadmap for the fuel cell and hydrogen technology developments. If the final goal is broken down into the performance of polymer electrolyte materials, minor changes to materials that have already been developed or are on the market will not be able to meet that demand. A major technical breakthrough will be required in the next 10 years, and a new concept will be required to achieve it. After showing the research background of polymer electrolyte membranes, this report overviews the current issues of polymer electrolyte membranes, especially the response to the NEDO roadmap for fuel cell and hydrogen technology developments.
