摘要： An apparatus removes carbon monoxide (CO) from a hydrogen-rich gas stream in a hydrogen fuel cell system. CO fouls costly catalytic particles in the membrane electrode assemblies of proton exchange membrane (PEM) fuel cells. A vessel houses a carbon monoxide adsorbent. The vessel may be a rotating pressure swing adsorber. A water gas shift reactor is upstream of the rotating pressure swing adsorber. The water gas shift reactor may include a second adsorbent adapted to adsorb carbon monoxide at low temperatures and to desorb carbon monoxide at high temperatures. The apparatus advantageously eliminates the use of a preferential oxidation (PROX) reactor, by providing an apparatus which incorporates CO adsorption in the place of the PROX reactor. This cleans up carbon monoxide without hydrogen consumption and the concomitant, undesirable excess low grade heat generation. The present invention reduces start-up duration, and improves overall fuel processor efficiency during normal operation.
摘要翻译： 装置从氢燃料电池系统中的富氢气流中去除一氧化碳（CO）。 CO在质子交换膜（PEM）燃料电池的膜电极组件中产生昂贵的催化颗粒。 船只装有一氧化碳吸附剂。 容器可以是旋转的变压吸附器。 水煤气变换反应器位于旋转变压吸附器的上游。 水煤气变换反应器可以包括适于在低温下吸附一氧化碳并在高温下解吸一氧化碳的第二吸附剂。 该设备有利地消除了优先氧化（PROX）反应器的使用，通过提供一种在COX反应器的位置引入CO吸附的装置。 这样可以清除一氧化碳，而不会产生氢气消耗，同时伴随着不希望有的过剩低级发热。 本发明减少启动持续时间，并且在正常操作期间提高总体燃料处理器效率。

摘要： An ion conducting polymeric structure suitable for fuel cell applications is provided. The polymeric structure comprises a non-homogenous polymeric layer. The non-homogeneous layer is a blend of a first polymer comprising cyclobutyl moiety; and a second polymer having a non-ionic polymer segment. The weight ratio of the first polymer to the second polymer varies as a function of position within the non-homogenous layer. The blend composition may be cast into an electrolyte membrane that can be used to prepare electrochemical cells such as batteries and fuel cells.

摘要： Substantially all of the carbon dioxide is removed from a gas containing up to about 1% by volume carbon dioxide by subjecting the gas to a pressure swing adsorption process using as the adsorbent a single layer of zeolite having a silicon to aluminum atomic ratio in the range of 1.5 to 70. The process is particularly suitable for removing substantially all carbon dioxide and water vapor contained in air prior to subjecting the air to cryogenic distillation.
