Abstract: Liquid cooled systems having coolant circulation loops must often operate in below freezing conditions. For instance, in various applications certain fuel cell systems must be able to tolerate repeated shutdown and storage in below freezing conditions. Conventional glycol-based coolants typically used for internal combustion engines are generally unsuitable for use in the associated fuel cell cooling subsystems due to the presence of additives and/or inhibitors which are normally included to deal with problems relating to decomposition of the glycol. With additives or inhibitors present, the coolant conductivity can be sufficiently high as to result in electrical shorting or corrosion problems. However, provided the purity of the coolant is maintained, a pure glycol and water coolant mixture may be used as a fuel cell system coolant to obtain suitable antifreeze protection. Adequate purity can be maintained by including an ion exchange resin unit in the cooling subsystem.

A RuxSe catalyst is prepared with comparable catalytic activity to platinum. An environmentally friendly aqueous synthetic pathway to this catalyst is also presented. Using the same aqueous methodology, ORR catalysts can be prepared where Ru is replaced by Mo, Fe, Co, Cr, Ni and/or W. Similarly Se can be replaced by S.

Abstract: In a solid polymer fuel cell series, various circumstances can result in a fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel. In order to pass current, reactions other than fuel oxidation can take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter can result in significant degradation of the anode, particularly if the anode employs a carbon black supported catalyst. Such fuel cells can be made substantially more tolerant to cell reversal by using certain anodes employing both a higher catalyst loading or coverage on a corrosion-resistant support and by incorporating, in addition to the typical electrocatalyst for promoting fuel oxidation, certain unsupported catalyst compositions to promote the water electrolysis reaction.

Abstract: An adhesive composition comprises at least a binder polymer and a water-soluble plasticizer. The binder polymer may be present in a range of about 10% to about 60% by weight of the adhesive composition, and the plasticizer may be present in the range of about 5% to about 85% by weight of the adhesive composition, such as in the range of about 40% to about 80% by weight. In some aspects, the adhesive also comprises less than 10% by weight highly-volatile component, such as about 0% to about 5% by weight. The adhesive composition can be utilized in a variety of articles, including personal care articles, health/medical articles, and household/industrial articles.

Abstract: Corrosion of the carbon catalyst support may occur at both the anode and cathode catalyst layers within an electrochemical fuel cell. Such corrosion may lead to reduced performance and/or decreased lifetimes of the fuel cell. Nevertheless, carbon supports have many desirable properties as catalyst supports including high surface area, high electrical conductivity, good porosity and density. To reduce or eliminate corrosion of the carbon catalyst support, the carbon support may have a metal surface treatment and, in particular, a metal carbide surface treatment. Suitable metal carbides include titanium, tungsten and molybdenum. In this manner, the metal carbide surface treatment protects the underlying carbon support from corrosion while maintaining the desirable characteristics of the carbon support.

Abstract: Corrosion at the cathode catalyst may be a serious problem compromising fuel cell lifetimes. However in providing for increased corrosion resistance, an expected trade-off may occur regarding fuel cell performance. TKK (Tanaka Kikenzoku Kogyo) has solved this problem by providing both increased corrosion resistance with no concomitant loss in performance with their catalysts TEC50EA10 and TEC50BA10. An alternative to the TKK catalysts is to use an admixture of platinum black and supported catalyst and in particular, an admixture comprising 30-40% by weight platinum black and 60-70% by weight supported catalyst.
