Flow cell systems, flow cell batteries, and hydrogen production processes
Flow cell systems are provided. Example flow cell systems can include an H+/H2 half-cell and a counterpart Fe3+/Fe2+ or V5+/V4+ half-cell. Flow cell systems can also include a half-cell in fluid communication with an electrolyte regeneration chamber. Embodiments of these flow cells systems can be configured to produce hydrogen through electrolysis. Flow cell battery systems are also disclosed. Example flow cell battery systems can include an H+/H2 analyte; and a counterpart Fe3+/Fe2+ or V5+/V4+ catholyte. Processes for generating hydrogen are also disclosed. Example processes can include generating protons from a Fe3+/Fe2+ or V5+/V4+ electrolyte solution; and reacting the protons with H2O to form H2.
