(1)研究開発の目的
固体高分子形燃料電池(以下燃料電池)の市場化において、定置型燃料電池システム(エネファーム)については既に販売が始められており、燃料電池自動車についても2015 年に普及開始が予定されている。一方、これからの本格的普及には燃料電池システムの大幅なコスト低減が大きな課題となっている。
英文要約Title: Strategic Development of PEFC Technologies for Practical Application/Development of Technology on Basic and Common Issues/Analysis of Morphology, Reaction Mechanism, And Mass Transfer Phenomena for MEA Materials (FY2010-FY2012) FY2010 Annual Report
The objective of this project is to clarify the rate determining parameters for reactions and mass transfer phenomena in MEA which contribute the development of new materials and simplifications of fuel cell system. The target is to develop the analytical and measurement methods about the morphologies and properties of materials in MEA of PEFC. 1) Research field of electrolytes; Micro or meso-scale observation methods of morphologies and measurement methods of gas permeation and proton conduction thorough the electrolyte materials were progressed. Especially, we have succeeded to improve high temperature measurements for e-AFM, NMR, and ATR-IR. The numerical simulation methods for visualization of morphology of water channel in electrolyte materials were also established. Uniform model electrolyte materials controlled the structure have been synthesized. 2) Research field of electrode-reaction; The formation of OH group on cathode catalysts were simulated by using MD method under controlled potentials. For methodology to complement to numerical method by experiments, the surface enhanced IR spectroscopy has been developed. For analysis of fine structure and electronic state of electrode-catalyst in real time observation, Time- and Space-resolved XAFS system has been developing. The University of Electro-Communications constructs a new beam-line named as "Advanced Beam Line for Real Time Measurement Catalyst Structure and Reaction Dynamics" at SPring-8. The grand design of components was completed, and some parts were fabricated. According to development of the polarization dependent total reflection XAFS, high S/N ratio spectrum was obtained. As model materials, catalysts which distance between particles are controlled uniformly about 2nm has been synthesized.  3) Research field of materials transportation in the catalyst layer; The prototype of simulator to simulate the proton conduction and oxygen permeation thorough ionomer material covered on Pt particle was constructed. Development of multi-scale MD simulation was also progressed. Modeling of the energy and mass transport in MEA was being carried out for estimating the temperature profile in the MEA. Effective thermal conductivity of the catalyst layer has been measured and the oxygen reduction reaction has been analyzed. Water behavior in MEA was investigated by using soft X-ray radiograph for macroscopic scale and small angle neutron scattering method for microscopic scale. NMR study about water behavior in MEA under lower humidity condition was also investigated.
