英文要約Title: New Energy Venture Business Technology Innovation Program/ New Energy Venture Business Technology Innovation Program (Fuel Cells and Batteries)/ Technology Development of high conductive Diamond Like Carbon separator by high speed film formation

Right now, material of substitute used to PEFC (Polymer Electrolyte membrane Fuel Cell) separator is carbon. In 2015, mission is that recent cost will be one third (150 yen per sheet) in nearly future. SUS316L with the superior corrosion resistance is expected to next generation separator, but deterioration of the electrolyte membrane by the metal elution becomes the big problem.  Film of DLC, which Plasma Ion Assist developed by the PBIID (Plasma Based Ion Implantation and Deposition) method, is a minute conductive made by heating of number 100 degrees Celsius, high-energy carbon and boron ions implantation and deposition. A electric resitivity is less than 5 mohms・cm, and the contact resistance is 5 mohms・ cm2, too. I show the value that I should be satisfied with as a separator.  One of the technical problems is when SUS316L which coated conductive DLC immerses in electrolyte of the sulfuric acid (pH2) of temperature 70 degrees Celsius and the voltage 0.8V, it is not eroded DLC and metal does not leach from the SUS316L. As for the metal ion concentrations 24 hours later, ratio 0.01ppm or less of the nickel ion are found. PIA conductive DLC achieves this aim.  There is it whether problem 2 is possible in 150 yen/piece or less with separator matrix, processing, coating cost. PIA PBIID's speed of film formation using ICP (Induction Coupled Plasma) is superior to normal film formation speed. It is a 20um/h. As for the coating cost, 20 yen - 30 yen are expected in a separator of 10cm2. PIA carries this target out in 2011.
