Abstract
Some embodiments of the present invention provide a balance-of-plant system and apparatus suited for regulating the operation of an electrolyzer cell stack. Specifically, in some embodiments, a balance-of-plant system and apparatus is operable to regulate the respective pressures of at least two reaction products relative to one another. Various examples are provided to demonstrate how the respective pressures of two reaction products can be regulated in relation to one another in a pressure following configuration, thereby regulating the pressure differential across an electrolyte layer according to aspects of different embodiments of the invention. Some of the examples provided also include design simplifications and alternatives that may reduce production costs of electrochemical cells configured according to aspects of different embodiments of the invention.
