Analysis of the Impact of Individual Glass Constituents on Electrocatalysis on Pt Electrodes in Alkaline Solution

In the previous paper [ibid., P1 (2008)] the authors reported on the impact of glass corrosion on establishing the electrocatalytic activity of fuel cell catalysts. The leaching of glass constituents into the electrolyte is responsible for insufficiently reproducible measurements of the oxygen redn. reaction as well as the hydrogen oxidn. reaction on polycryst. Pt. The authors elucidate which glass constituents are leached into the electrolyte through the anal. of alk. electrolytes in contact with Duran glass by inductively coupled plasma optical emission spectroscopy. By adding these constituents, i.e., silicates, borates, aluminates, and lead, sep. to the electrolyte, the authors evaluate their individual impact on electrocatalytic measurements. The results presented in this study help to explain the effects seen in measurements in alk. electrolyte with glass cells. [on SciFinder(R)]     «
