일본의 신에너지 종합개발기구(NEDO)는 최근 「중장기계획-신에너지개발의 과제와 전망 」이라는 보고서를 발표했다. 이 중장기계획은 NEDO가 80년 10월에 관민활동으로 설립된 이후 처음으로 입안한 것이며, 그동안의 연구성과를 발판으로 향후 3년에 걸쳐 달성해야 할 사업목표와 중장기 전망에 대한 검토한 것으로 이른바 NEDO의 활동지침이라고 할 수 있겠다. 그 전문을 옮겨 싣는다. <편집자주>

Degree of membrane degradation in Proton Exchange Membrane Fuel Cells (PEMFC) is mainly evaluated by the hydrogen crossover current density. The hydrogen crossover current density is measured by linear sweep voltammetry (LSV), which differs from the DOE protocol and the NEDO protocol. In this study, two protocols were compared during PEMFC operation and accelerated stress test. In the LSV method by the DOE method, the scan rate change affects the hydrogen crossover current density, but the NEDO method does not affect the hydrogen crossover current density. In the course of 15,000 cycles of polymer membrane wet/dry cycle, the DOE method was sensitive to membrane degradation, but the NEDO method was less sensitive to membrane degradation than the DOE method.

New Energy and Industrial Technology Development Organization (NEDO) promotes R&D that individual private sector enterprises can not undertake by themselves. To do this, it utilizes an extensive network that supports cooperation between industries, universities, and public research organizations. NEDO's government-funded R&D budget for FY2005 totals approximately 148.8 billion yen. Fuel cells and hydrogen technology development project is one of NEDO's emphasizing projects. The budget size was ${\yen}$20.8 billion, corresponding to about 60% of annual expenditure of Japanese government for fuel cells in FY2005. These projects consist of 8 programs as follows.

High functional micro devices are demanded in a variety of fields. For realising such demands, development of high-precision micro-components installed in the devices are needed. To achieve high-precision in the mold processing of micro-components, the development of mold materials, i.e., the development of WC-Co hardmetal with higher hardness and fracture strength is essential, together with the developments of processing technology of high precision mold and mold-forming technology of high precision micro-components, etc. The role of development of the finer submicro-grained hardmetal in a NEDO national project aiming the integrated development of these all technologies and some results are mainly explained.

Hydrogen permeability is widely used to evaluate the polymer membrane durability of polymer electrolyte fuel cells (PEMFC). Linear sweep voltammetry (LSV) is mainly used to measure hydrogen permeability easily. There are many differences in LSV measurement method among researchers, and it is often difficult to compare the results. Therefore, in this study, we tried to confirm the accuracy by comparing the hydrogen permeability of LSV method and gas chromatograph which is difficult to measure but accurate value. The LSV method used the DOE and NEDO methods. When the hydrogen permeability was measured by varying the temperature and the relative humidity, the DOE LSV method showed an accuracy of less than 5% in the error range compared with the GC method. In the NEDO LSV method, the error was reduced when the hydrogen permeation current density was determined at the current value of 0.3 V as the DOE method.
