The Center has been investigating new catalysts and membranes for polymer electrolyte fuel cells with high performance, reliability and low cost under the “HiPer-FC (High Performance Fuel Cell)” project funded by NEDO, Japan (starting in April, 2008). The project was rewarded with the development of superior materials and a number of new scientific insights, as shown below: Stabilized Pt-skin alloy catalysts; conducting ceramic supports with fused-aggregated network structure, with excellent stability during potential variation; and hydrocarbon electrolyte membranes, with similar proton conductivity and higher durability compared with the fluorocarbon electrolyte membranes.
The present “S-Per-FC” (Superlative, Stable, and Scalable Performance Fuel Cell) project started in May, 2015 with funding from NEDO, Japan, in which our Center is the core of the project organization. The main purpose of the project is to contribute strongly to the large-scale proliferation of fuel cells vehicles based on these superior outcomes. Membrane-electrode assemblies, in which both catalysts and membranes have shown limited performance, will be developed on the basis of scientific insights, and the performance will be elucidated by the use of state-of-the-art analytical systems. The new concept of high power, high durability and high efficiency materials will be pursued. Using this new concept, we will contribute to the development of low cost fuel cell vehicles, including commercial vehicles, using low amounts of precious metals and with higher durability.
In order to put the materials developed using these concepts into practical use by the next stage of proliferation of fuel cell vehicles starting in FY 2025, we will establish the fundamental technology by FY 2019, realizing a 10-fold increase in the cost performance based on the quantity (power density × lifetime) / (mass of precious metals) compared to that of the conventional fuel cell.
