| Outline of Research at the Start |
燃料から直接電気エネルギーを取り出す燃料電池は、エンジン発電機の倍以上の高い発電効率を有するにも関わらず、途上国での導入事例はほぼ皆無である。我々は、燃料電池の地球規模の普及に向け、水素インフラを必要としないバイオマス廃棄物を資源としたサイクルを提案し、その核となるバイオガスの直接供給で作動する革新的燃料電池技術体系の確立に向けた国際共同研究を、ベトナム国家大学ホーチミン市校（VNUHCM）・ナノテク研究所（INT）と実施する。

| Outline of Final Research Achievements |
For the reduction of environmental load in a rural area of developing countries, materials development was addressed to contribute to the systematization of direct-biogas fuel cell technology for creating a new trend of material and energy circulations using regional biomass resources. A novel process to obtain a desulfurizer made from a local biomass waste and a novel structured-catalyst, which can be applied on the anode of solid oxide fuel cell (SOFC), were tied to be developed. For the former task, it was found that a practical desulfurizer can be obtained by the treatment of a biochar delivered from rice husk with NH3 evaporated from an aqueous solution simulating a digested liquid. For the latter task, a paper-structured catalyst with a dispersion of Ni-loaded flowerlike Ce0.5Zr0.5O2, which can reduce the risk of coking during the SOFC operation directly fueled by biogas, could be developed.
