## Abstract In this work, the effect of platinum percentage on the carbon support of commercial catalyst for electrodes to be used in a Polybenzimidazole (PBI)โbased PEMFC has been studied. Three percentages were studied (20, 40 and 60%). In all cases, the same quantity of PBI in the catalyst layer

Abstrad-Based on the adsorption-rate equation derived in Part I of this investigation, a differential equation has been obtained for the prediction of the concentration distribution in activated carbon columns. This differential equation derived without the constant pattern assumption has been solve
A faint chemiluminescence (CL) from the neutralization reaction of nitric acid and potassium hydroxide was enhanced by addition of iron(U) to the acid. The enhanced CL emission was suppressed by adding inorganic anions such as chloride, bromide, nitrite, nitrate and sulfate to the base. Based on the
Ah&act-Mass transfer coefficients for external and internal transport were determined using experimentally established time-concentration curves in batch tests for the adsorption of organic impurities from water on activated carbon particles. These tests revealed that the mass transfer coefficient f
