Corrosion resistance of dental precious metal alloys in pseudo-oral environment

Publikováno v: 松本歯学. 33(2):200-209

The corrosion resistance of twelve commercially available dental precious metal alloys, pure titanium and Ti6A14V alloy was investigated by measuring anodic polarization and open-circuit potential in de-aerated 1 mass%-lactic acid solution. The open-

Polymer electrolyte fuel cells operation under low pressure condition

Autor: Naito, Hitoshi, Segami, Go, Kibe, Koichi, Sone, Yoshitsugu, Uno, Masatoshi

We clarified the criteria for 100 W-class operation of the fuel cell system. We tested the fuel cell performance by the operation under low pressure condition (approximately 3 kPa). We operated the fuel cell without external humidifier and thermal co
