Catalyst Preparation by Dry Migration Method for Hydrogen Concentration Cell to Convert Heat into Electricity

将2-丙醇脱氢的吸热催化反应与氢和丙酮驱动的燃料电池相结合，提出了一种热再生燃料电池，由电极催化剂和聚合物电解质膜组成。低质量的热量，如太阳能和地热能或工厂中的废热，通过该装置系统转化为电能，牺牲了将热量排出到环境环境中，以便通过分馏分离2-丙醇和丙酮。值得注意的是，丙酮的氢化在电化学上比分子氧更容易，因为羰基的质子化和还原比O-O三键的裂解容易得多。这种电化学转化不仅适用于氢与丙酮的阴极/阳极偶联，也适用于氢通过2-丙醇脱氢从金属细颗粒溢出到催化剂碳载体上。此外，催化剂金属颗粒的溢出能力和脱氢活性不是由平衡因子决定的，而是受动力学控制的。旨在开发适合于2-丙醇脱氢和氢气溢出的催化剂。采用干迁移和钯催化剂与钌羰基团簇配合物在氢气氛下反应的方法，制备了高孔碳负载的双金属纳米级颗粒。以高脱氢活性和氢气溢出为研究对象，取得了显著的效果。电化学测量由电工实验室的一个研究小组进行。MITI，其中合理的电压电流关系和开路电压在不同的温度被证明。

A thermo-regenerative fuel cell has been proposed by combining an endothermic catalylic reaction of2-propanol dehydrogenation with a fuel cell driven by hydrogen and acetone, being constituted with electrode catalysts and a polymer electrolyte membrane. Low-quality heats such as solar and geotherinal heats or waste heats in factories are converted into electricity by this device system at the sacrifice of heat removal into ambient circumstances in order to separate 2-propanol and acetone by fractional distillation. It is to be noted that acetone is hydrogenated more electrochemicaly facile than molecular oxygen, because the catbonyl protonation and reduction proceeds much casier than cleavage of the O-O triple bond.Not only the cathode/anode couple of hydrogen versus acetone but also the hydrogen spillover onto the catalyst carbon support from the metal fine particles through 2-propanol dehydrogenation are applicable to this electrochemical conversion. Moreover, the spillover ability as well as dehydrogenation activity of catalyst metal particles are not determined by an equilibrium factor but under a kinetical control.Aiming at the development of suitable catalysts for 2-propanol dehydrogenation and hydrogen spillover. preparation of bimetallic nano-size particles supported on highly-porous carbon has been attempted by applying the method of dry migration and reaction between a palladium catalyst and ruthenium carbonyl cluster complexes under hydrogen atmosphere. Appreciable results were obtained for the research object of high dehydrogenation activity and hydrogen spillover.Electrochemical measurements were performed by a research group in Electrotechnical Laboratory. MITI, in which reasonable voltage-current relationships and open-circuit voltages at various temperatures were demonstrated.
