Abstract

A multi-stack electrochemical hydrogen compressor (EHC) system is provided. The EHC system may have two or more EHC stacks, wherein each EHC stack includes at least one electrochemical cell and a power supply. The EHC system may also have a controller in communication with the power supply of each EHC stack, wherein the controller is configured to reduce total energy consumption of the EHC system by independently controlling the power supply of each EHC stack.

Description

[0001] This application claims the benefit of US Provisional Application No. 62 / 020,030, filed July 2, 2014, which is incorporated by reference in its entirety. technical field [0002] The present invention is directed to multi-stack electrochemical compressor (EHC) systems and methods of operation, and more particularly, to multi-stack EHC systems and methods for optimizing electrical power consumption. Background technique [0003] Hydrogen has emerged as a viable alternative to traditional energy sources. The successful commercialization of hydrogen as an energy carrier and the long-term sustainability of the "hydrogen economy" is largely dependent on the efficiency of hydrogen fuel cells, hydrogen electrolyzers, hydrogen production, hydrogen processing / management systems (e.g. compressors), and hydrogen distribution systems and cost-effective. Gaseous hydrogen is a convenient and efficient method of energy storage, usually through a pressurized volume. Advantageously,...
