Mixtures of hydrogen with common hydrocarbon fuels are considered viable for reducing carbon footprint in modern industry, power production, and transportation. The addition alters the kinetics thermophysical properties mixtures, as well composition combustion products, requiring detailed research into features flame propagation hydrogen-enriched hydrocarbon–air mixtures. Of particular interest also safety aspects such fuels. In this paper, experimental results presented on premixed laminar channels formed by two closely spaced plates (Hele-Shaw cell), internal straight walls forming a diverging (diffuser) channel opening angles between 5 25 degrees. Methane–hydrogen–air mixtures relative contents 0%, 25%, 50% global equivalence ratio unity were ignited spark near closed narrow end channel. Experiments performed gap width 3.5 mm; video recordings processed order to determine quantitative front (leading trailing point coordinate, coordinates cusps, cell sizes shapes). main (fast initial expansion, development cellular flame, self-induced longitudinal oscillations) obtained compared clarify effect fuel geometry (gap width, angle).

The integration of renewable energy sources, such as wind and solar power, at high proportions has become an inevitable trend in the development power systems under new system framework. construction a microgrid incorporating hydrogen storage battery can leverage complementary advantages long-term short-term hybrid storage, achieving balance across multiple time scales system. To prevent frequent start-stop cycles devices lithium overcharge overdischarge conditions, coordinated control strategy for distribution with is proposed. First, fuzzy algorithm used between storage. Then, tank’s state health (SOH) battery’s charge (SOC) are compared, goal selecting multi-stack fuel cell operating its optimal efficiency point, where each stack outputs 10 kW. This further ensures that SOC SOH remain within reasonable ranges. Finally, simulations conducted MATLAB/Simulink R2018b to verify proposed maintains stability DC bus alleviates issues overdischarge, ensuring both system’s range, thereby enhancing equipment lifespan stability.
