摘要：

Experimental results are presented for the coupled metal-hydride reactors of Ca(0.4)Mm(0.6)Ni(5) (Mm = misch metal) with hydrogen pumped by the compressor. In order to-augment the heat transfer in the reactor, metal hydride powders were copper-coated and compressed into a porous metal hydride (PMH) compacts. The reactors, packaged with these PMH compacts, produced continuous cooling output of approximately 0.8 kW/kg of Ca(0.4)Mm(0.6)Ni(5) when the cycle time was set at 4 minutes. The experimental results indicate that optimized reactors of viable specific powers can be fabricated. In addition, comparisons between experimental and theoretical work are in a good agreement.
