| Research Abstract |
One awkward problem of the hydrogen fuel cell (HFC) is the serious poisoning of the Pt-electrode by a trace amount of CO in H_2. To avoid it, CO in H_2 is desired to be lower than 10ppm, and the CO in H_2 is usually removed by performing a preferential oxidation (PROX) reaction of CO by using Rh-base catalyst at around 160℃. If we could develop a low temperature active catalyst (<80℃), we can operate HFC by H_2 containing CO without purification. We have developed three extremely active new catalysts, which are FeOx/Pt/TiO_2, FeOx/Au/TiO_2, Pt on carbon nano-tube. By using one of these catalyst, we operate a polymer electrolyte hydrogen fuel cell in H2 containing 1,000ppm CO for more than 6 hours without drop of the power.
