Polymer Materials for Progress of PEFC

POLYMERS, 2003
電解質膜はPEFCのキーマテリアルである。イオン伝導性だけでなく,電極触媒の活性に大きな影響を与えてPEFCの性能を左右するNafionの開発とNafionを低級アルコールに溶かした溶液の開発は燃料電池の開発の中で大きなブレークスルーをもたらした。自動車用,家庭用として大規模にPEFCが普及するためにはイオン導電性,耐熱性,化学的安定性,機械的強度のさらなる向上などに加えて,大幅なコストダウンが望まれる。

PEFC in Germany

, 2001
La certification forestière PEFC a connu un succès rapide en Allemagne : en à peine plus d'un an, d'août 2000 à octobre 2001, plus de 4,9 millions d'hectares ont été certifiés. Le système de certification adopté se base sur une forte implication des propriétaires (publics et privés), sur une volonté d'ouverture à toutes les parties intéressées et sur ...

Effects of the operational conditions on the membrane and electrode properties of a polymer electrolyte fuel cell

Journal of the Brazilian Chemical Society, 2002
The effects of the operational conditions on the membrane and electrode properties on a polymer electrolyte fuel cell (PEFC) were investigated as a function of the cell and the gas humidifiers temperatures, the thickness of the membrane, the impregnation
