已生产出厚度达50 μ m的薄钯及钯合金膜管。这些金属膜用作水煤气变换反应的催化膜反应器中的管式渗透器，比市售的金属膜（100-150 μ m）薄，并且具有对氢的完全选择性和良好的耐久性。一个制造过程，包括几个步骤的冷轧和退火的金属箔加上一个简单的焊接技术的管已经进行，以生产原型薄钯渗透器。详细描述了钯和钯合金箔的轧制和退火过程：通过硬度测量控制了钯和钯合金箔轧制时的加工硬化。对水煤气变换反应膜和CMR的模型研究和测试表明，在核聚变燃料循环和燃料电池加燃料等能源应用中分离和回收高纯氢是可能的。(C)2000年国际氢能协会。由Elsevier Science Ltd.出版，版权所有。
Thin palladium and palladium alloy membrane tubes with thickness up to 50 mu m have been produced. These metal membranes, used as tube permeators in catalytic membrane reactors for the water gas shift reaction, are thinner than the commercial ones (100-150 mu m) and have both complete selectivity to hydrogen and good durability. A manufacturing procedure consisting of several steps of cold-rolling and annealing the metal foils coupled with a simple welding technique of the tubes has been carried out in order to produce the prototype thin palladium permeators. The procedure of rolling and annealing the palladium and palladium alloy foils is described in detail: the work hardening upon rolling of the palladium and palladium alloy foils has been controlled by means of hardness measurements. Model studies and tests on the membranes and the CMRs for the water gas shift reaction have demonstrated the possibility to separate and recover highly pure hydrogen in energy applications such as nuclear fusion fuel cycle and fuel cells fuelling.
