A technique developed by Studebaker and Snow was used to determine the contact angle of water (cos e,,) on porous carbons which were electrochemically treated in phosphoric acid. Electrochemical oxidation resulted in a decrease in cos t& whereas, electrochemical reduction resulted in an increase in

An experimental program was conducted to investigate the catalytic activity of platinum black and platinum supported on carbon for the electrochemical reduction of oxygen in 99 wt% phosphoric acid at 177'C as a function of platinum surface area. The activity of platinum was found to approximately do
The influence of linear solution flow past a horizontal anode on its mode and rate of dissolution has been examined for pure polycrystalline and single-crystal copper in 4, 6, 8 and 10 M aqueous o-phosphoric acid. In 4 M acid, copper dissolves with crystallographic etching at all potentials and flo
