英文要約Title: Development of PEFC Technologies for Commercial Promotion, Base Technology. Basic and common technology for cell evaluative analysis. (FY2010-FY2014) FY2013 Annual Report

The following five items were carried out in the 2013 fiscal year. (1) MEA manufacturing processes corresponding to new material: The spray transfer method which transfers the catalyst layer which carried out the spray application on the Teflon sheet by a hot-press on an electrolyte membrane was performed. While securing the good MEA performance, the yield of catalyst ink could also improve, and correspondence also for a small-quantity catalyst was attained. (2) MEA material evaluation technique corresponding to new material: The influence which a diagnostic item (LSV, a conditioning, IV measurement) has on a durability test result was evaluated in the middle of under OCV holding test. Moreover, the end conditions of the start and stop cycle test were improved. The durability of Nafion HP was evaluated using the cell evaluation protocol set up in the 2012 fiscal year as an object for comparison of a NEDO’s next-generation development electrolyte membrane. The quality assessment result of MEA obtained by the MEA material cell evaluation technique upon which it decided in the project by the 2012 fiscal year was analyzed from a viewpoint of reliability, reproducibility, and variation. (3) Development of an analysis evaluation technique: The evaluation of fine-pores area of the catalyst layer cross-sectional observation by the FIB/FE-SEM method was attained by development of the burial technique and observable range extension technology. About the water transfer analysis inside MEA, the measuring technique of the electro-osmotic water at the time of power generation was developed, and data was acquired. Moreover, in consideration of the influence of diffusion water, the water transfer analysis technique which predicts membrane performance was built. The basic technique by a boring test was developed as electrolyte membrane degradation mapping technology. (4) The proposal of the new material improvement direction: With the evaluation technique according to a common protocol, cell evaluation of catalysts developed by NEDO projects, next-generation development electrolyte membranes and newly developed material as the reference was performed and the evaluation result was fed back to the developer. (5) Impact evaluation of hydrogen impurities: The mode of operation which simulates a real drive of FCEV was set up, and modes-of-power-generation evaluation which used as fuel hydrogen containing CO was performed. Moreover, the influence by the load cycle and start and stop cycle was evaluated for poison and recovery mechanism evaluation. The impurities covering analysis model at the time of, using as fuel hydrogen gas containing CO which predicts the anode catalyst CO covering rate and anode over-voltage on various operating conditions was built. Moreover, power generation evaluation of the influence of H2S in fuel concentration exerted on cell voltage down was carried out.
