Disclosed are an antioxidant for a fuel cell having a high degree of dispersion and/or distribution and excellent antioxidant capability and a membrane-electrode assembly including the same. The antioxidant includes a metal oxide and a sulfur- containing organic compound, for example, an organic compound including a sulfinic acid anion group (R—SO.sub.2.sup.−), adsorbed on the metal oxide.

Methods are provided to inhibit corrosion in low hardness water systems. The corrosion inhibiting treatment comprises: calcium salts of low molecular weight polymer polycarboxylic acids. These calcium salts may be added preformed to the water system in need of treatment or formed in-situ in the system. This method of corrosion inhibition is not a source of addition phosphorous or heavy metal to the treated system.

Methods and compositions for inhibiting carbonyl-based fouling of basic wash systems. The methods comprise contacting the hydrocarbon stream that is or will be subjected to such washing with water soluble or water dispersible copolymers comprising repeat units of 1) ethylenically unsaturated monomers such as acrylic acid with one or more 2) other repeat units such as alkyl acrylates, allyl ethers, ethoxylated allyl repeat units, etc. In other embodiments, a third repeat unit 3) is present and may comprise a hydrophobic moiety such as a styrene repeat unit. The compositions may be terpolymers comprising repeat units 1), 2), and 3).

Disclosed herein are sulfur-functional corrosion inhibitors that are adducts of a cyclic anhydride with 2-mercaptoethanol. Concentrates of the sulfur-functional corrosion inhibitors do not degrade to form H.sub.2S under standard storage conditions for a period of up to 5 years. Also disclosed herein are treated water sources and treated metal containments including one or more sulfur-functional corrosion inhibitors. The sulfur-functional corrosion inhibitors inhibit corrosion of metal containments contacted with one or more water sources, wherein the one or more water sources comprise one or more corrodents. The sulfur-functional corrosion inhibitors are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight or a volume basis.
