Graphene is a porous medium that serves as storage for hydrogen. Energy in the form of H-atoms is adsorbed and desorbed within the employed graphene slurry in the system. Graphene in the slurry form, when contained in a closed container, is non-toxic and does not emit any harmful fumes.

The amount of energy produced and stored depends upon the operational parameters viz. the flow rate of reactants, etc. However, under ideal conditions a RFC system could store and supply energy equivalent to 546 mAh/g. The energy storage density of a reversible fuel cell is comparable with that offered by commercially available lithium-based batteries.

AEM is considered as a superior hybrid solution combining the benefits of both PEM electrolysers and Alkaline electrolysers. The major issue with PEM technology is the high cost owing to the use of precious metals such as Platinum and Iridium as catalysts. AEM does not require such precious metals making it more sustainable and cost effective than PEM electrolysers. The major drawback in Alkaline electrolysis is its low current density and highly corrosive alkaline solution used as the electrolyte. The AEM technology offers higher current density using significantly reduced amounts of corrosive electrolytes compared with alkaline electrolysers.

Cipher Neutron’s AEM electrolysers are up to 82% efficiency and much higher current density of 2 amps/cme as compared to traditionally available alkaline electrolysers with 0.07 amps/cm2 current density. This cost reduction in raw materials, the elimination of the use of Platinum group metals as catalysts, coupled with our unique design, allows the production of our AEM electrolysers at much affordable prices.

The hydrogen delivery pressure using our AEM electrolyzer could reach up to 25 bars.

Yes, external compressors can be used to increase the hydrogen and oxygen pressure as per requirements.
