Theoretical models of coupled metal hydride reactors are necessary for design and optimization studies and must be formulated for an entire system in order to have useful predicative capability. The archtypical system (which may be used as a heat pump or for hydrogen storage) includes two reactors with the active and inactive constituents forming a porous matrix which must accommodate heat and hydrogen transfer at high rates. When the heat transfer between reactors and their surroundings, as well as the time varying boundary conditions which occur in actual operation are considered, a comprehensive system theory becomes extremely complicated, even at the one-dimensional level. Idealizations and compromises are required in order to obtain a theory which can be solved and which captures the essential features of experimental systems. This paper addresses the major problems that arose in the development of such a comprehensive theory and discusses the compromises that were required in order to obtain a solution.
