An electrolytic reaction system for generating gaseous hydrogen and oxygen includes a reaction chamber for accommodating an electrolyte as well as an electrode arrangement, which is formed of anodic and cathodic electrodes. Between lateral surfaces of electrodes arranged to be spaced apart from one another, at least one flow channel for the electrolyte is formed, which extends between a first axial end for admitting the electrolyte into the electrode arrangement and a second axial end for discharging the electrolyte out of the electrode arrangement. The at least one flow channel has at least one first flow cross-section and at least one second flow cross-section, wherein the second flow cross-section has a smaller size than the first flow channel, and the comparatively smaller second flow cross-section is formed in a partial section of the at least one flow channel closest to the second axial end of the electrode arrangement.

A method and apparatus according to the invention is described, which in a first mode operates as an internal combustion engine delivering energy and in a second mode operates as a pulsed compression reactor converting electrical energy in the form of chemical compounds. In the second mode, at least one of the generated compounds is collected and temporarily stored.

A hybrid plug-in battery and hydrogen fuel engine vehicle with swappable modular hydrogen tanks and integrated with solar power generation system synergistically combines the advantages of electric vehicle, the solar powered electric vehicle, and the hydrogen fuel engine vehicle. This combination of battery electric vehicle and hydrogen fuel engine vehicle mitigates the issues of prolong charging time of battery electric vehicle and prohibitive high cost of fuel cell electric vehicle. This hybrid configuration of vehicle is able to take advantages of the electric vehicle charging station infrastructure and the hydrogen charging station infrastructure simultaneously. The introduction of the water electrolysis system into the new structure of the hybrid vehicle enables onboard hydrogen generation; has the advantage of conventional hybrid vehicle, but without using fossil fuel. The swappable hydrogen tanks comprise sensors and wireless communication electronic terminals to be shared by all vehicles.

Various embodiments of systems and methods for a smart hydrogen injection controller are disclosed herein. The system produces hydrogen and oxygen from a Proton Exchange Membrane (PEM) electrolyzer and injects these gases individually into a combustion engine using port injection or direct injection at each cylinder of the combustion engine. In one aspect, varying the ratio of hydrogen to oxygen works to improve the operation of the internal combustion engine to decrease emissions and increase combustion efficiency.
