Popis: After low pressure hydrogen production by electrolysis of water, compression is required to increase the storage pressure in the final containers. The use of metal hydride materials seems to be a very effective way to increase the pressure of stored hydrogen. Heating these alloys significant increase the hydrogen pressure. The article describes the design of the compressor for using the generated heat at absorption process of the hydrogen into metal alloy during compression process. The equilibrium pressure, by which the absorption process occurs, is highly dependent at temperature of alloy. Difference in equilibrium pressures of MH materials at acceptable temperature change led to the effort to create a hydrogen compressor. The article describes the basic characteristic of hydrogen compressor and its actual state of development.
