英文要約Title:Development of PEFC Technologies aiming for Practical Application. Base Technology. Basic and common technology for cell evaluative analysis. (FY2010-FY2014) FY2012 Annual Report

The mission of “PEFC Evaluation Project” is to extract fine materials with high performance & low cost from many developing materials, and to help to accelerate the commercialization of Fuel Cell Electric Vehicles. The following 5 items were carried out in FY2012.
(1) Improvements of manufacturing processes and specifications for MEA of new materials. / The manufacturing processes of MEAs and the specifications of MEAs were verified again and were improved in order to evaluate correctly the abilities of catalysts and membranes which are being newly developed. In addition to usual transfer method, new spraying method was also developed which enabled direct coating of catalysts onto membranes. (2) Construction of evaluating methods applicable to MEAs of new materials. / Verifications of the validity of the test methods which FCCJ recommended in 2011 were carried out by the experiments with standard materials. Based on the knowledge from the results of the experiments, the systematic protocols to evaluate MEAs were edited to a booklet for general publication. (3) Construction of analytic evaluation techniques / Tokyo Institute of Technology shortened the time of observation of cut section of MEA by FIB-SEM method to conventional 1/3. Simultaneously, the sample holder of FIB was improved to rotate the cutting position of a sample in a chamber of FIB. Tokyo Institute of Technology improved the basic theories and fundamental techniques about analyzing the water movement inside MEAs, and applied them to the samples of electrolyte membrane developed by NEDO. Ritsumeikan University developed the technique which analyzes degradation of a membrane by a Nano-indenter, and basic technique to show the distribution of the degradation level in an electrolyte membrane. (4) The proposal for the improvement of new MEA materials. / By the methods according to common protocols Daido University and Japan Automobile Research Institute, JARI, evaluated the new MEA materials developed by NEDO, universities, national research institutes and companies. Daido University and JARI made clear the issues of new MEA materials based on the evaluation results, and presented to the developers the proposals for future improvements. (5) The influence of impurities in hydrogen fuel on the cell performance. / JARI prepared an MEA that reduced the anode platinum loading for the evaluation of impurities at various operating conditions. The influence of carbon monoxide was evaluated under various current density and load step conditions. A hydrogen recirculation system was installed for the investigation of impurity accumulation and operated under a load cycle condition.
