摘要： A membrane humidifier assembly for fuel cell applications includes a first flow field plate adapted to facilitate flow of a first gas thereto, a second flow field plate adapted to facilitate flow of a second gas thereto, and a polymeric membrane disposed between the first flow field plate and second flow field plate. The polymeric membrane is adapted to permit transfer of water. In order to prevent a perfluorosulfonic acid polymer, humidifier membrane from fouling and having diminished water vapor transport performance, ammonia and cation contaminants must be removed from the ambient gas streams. Suitable cationic and ammonia scavengers include filters comprising polymers functionalized with carboxylic acid groups, phosphonic acid groups, sulfonic acid groups, perfluorosulfonic acid groups or combinations thereof.

摘要： A method for removing SOx from a gas using an ethylene glycol composite solution is provided. The ethylene glycol composite solution is made by mixing ethylene glycol and/or polyethylene glycol with an organic acid and/or organic acid salt containing no nitrogen atom in a molecule, the ethylene glycol composite solution is brought into contact with the gas containing SOx to absorb the SOx in the gas, wherein x=2 and/or 3. The ethylene glycol composite solution with absorbed SOx is regenerated by one or more of a heating method, a vacuum method, a gas stripping method, an ultrasonication method, a microwave method, and a radiation method to release by-products of sulfur dioxide and sulfur trioxide, and the regenerated ethylene glycol composite solution is recycled for use. This method can be used for desulfurization of flue gas, burning gas, coke-oven gas, synthesis waste gas from dyestuff plants, sewage gas from chemical fiber plants, and other industrial raw material gases or waste gases containing SOx.
