英文要約Title: Development of Advanced PEFC Utilization Technologies /Development of Fundamental Technologies for PEFC Promotion /Highly-Coupled Analysis of Phenomena in MEA and its Constituents and Evaluation of Cell Performance (FY2015-FY2017) FY2016 Annual Report

The aim of this project is to clarify the controlling factor that influences loss and degradation of fuel cells and to support the technology development in the industries by analyzing the structure, materials property, process of structure formation, and physical phenomenon retrospectively under the subtopics : A for Electrocatalysis, B for Polymer Electrolyte Science, C for MEA Analysis, D for establishing the cell evaluation and analysis method for fuel cell, and expanding to research development. In FY2016, in Subtopic A, verification for Pt. particles size analysis technology under the practical condition, and the measurement technology that clarify the relation between catalytic activity and its structure were completed, and the phenomenon analysis has been started. An analysis technology development and inspection of interfacial structure and the electronic structure on electrocatalyst and ionomer have been progressed. In Subtopic B, the analysis of the effect of heat treatment and molecular structure on microphase-separated structure formation has been promoted by using the newly synthesized model electrolyte materials. The effects of wettability of carbon support, water content and thickness of ionomer on the proton transport and oxygen permeation were figured out by simulation.
In Subtopic C, a simple mathematical model for the analysis of power generation loss was developed. The detailed evaluation and analysis of the difference in ORR activity measured by RDE and real MEA has been started. The humidity influence on oxygen diffusivity in the catalyst layer was clarified. An in-situ PEFC evaluation analyses system was constructed on BL36XU beamline of Spring-8 and a high accuracy measurement of degradation phenomenon in various materials has been started. About the analysis of phenomenon during catalyst layer formation, the knowledge for the change of carbon agglomeration structure, development of ionomer network, and solvent drying mechanism were obtained by utilizing various analytical approach. In Subtopic D, developments of evaluation and analytical method for cells performance that meet high-performance-requirements of future market has been proceeded. In parallel to these works, we continued an evaluation and analysis of the materials from developers and provided feedback. The supports of evaluation and analysis by using synchrotron light source were also promoted under the scheme established in FY2016 for some NEDO-project-based institutions and researchers.
We have enhanced to expand the gains through the communication among the researchers of industry and university at the “FC-Cubic Technology Exchange Conference”.
