A novel design of a proton exchange membrane electrolyzer is presented. In contrast to previous designs, the flow field plates are round and oriented horizontally with feed water entering from central hole spreading evenly outward over anode in radial, interdigitated channels. The cathode consists spiral channel an outlet near outside bipolar plate. This results channels that run perpendicular avoid shear stresses. sealing concept requires only o-rings, which press against electrolyte countered by circular gaskets placed prevent penetrating channels, makes for much more economical compared prior designs using custom-made gaskets. Hydrogen leaves through vertical pipe off-center on top electrolyzer. stack housed cylinder capture oxygen vapor, then guided into heat exchanger section, located underneath partition. function preheat incoming fresh condense escape water, thus improving efficiency. It also serves as internal phase separator level sensor controls triggers recirculation pump condensate, while above can be connected vacuum allow operation at sub-ambient pressure further increase efficiency and/or reduce iridium loading.

The rational development of single-atom catalysts (SACs) for selective formic acid dehydrogenation (FAD) requires an atomic-scale understanding metal–support interactions and electronic modulation. In this study, spin-polarized density functional theory (DFT) calculations were performed to systematically examine platinum-group SACs anchored on graphitic carbon nitride (g-C3N4). findings reveal that Pd Au exhibit superior selectivity toward the pathway, lowering free energy barrier by 1.42 eV 1.39 eV, respectively, compared competing dehydration route. Conversely, Rh demonstrate limited due nearly equivalent barriers both reaction pathways. Stability assessments indicate robust driven d–p orbital hybridization, while a linear correlation is established between d-band center position relative Fermi level catalytic selectivity. Additionally, charge transfer (ranging from 0.029 0.467 e) substantially modulates structure active sites. These insights define key descriptor SAC design offer mechanistic framework optimizing hydrogen production.
