Abstract:
1. An chemical process system comprising: a fuel cell; a heat pump; and a chemical conversion unit capable of producing fuel for the fuel cell; wherein, during operation, the fuel cell produces heat at a first temperature; wherein, during operation, the heat pump increases the temperature of said heat to a higher temperature; and wherein, during operation, heat from the heat pump is transferred to said chemical conversion unit in a microchannel heat exchanger, wherein, when tested with nitrogen gas at inlet temperatures of about 23-26° C. and outlet temperatures ranging from 188 to 473° C. on the heat receiving side and inlet temperatures of 220-575° C. and outlet temperatures ranging from 61 to 145° C. on the heat rejecting side, the microchannel heat exchanger operates with an exergetic efficiency of at least 80%.
