The performance of high-temperature polybenzimidazole (PBI) proton exchange membrane fuel cells (HT-PEMFCs) doped with phosphoric acid is strongly influenced by the configuration its flow channel. In this research, genetic algorithm (GA) adopted to optimize original three-dimensional simulation model obtaining optimal design channel configuration. Set widths top and bottom edges anode/cathode channels as independent variables constrained range HT-PEMFC performance. ratio pressure drop loss...
Abstract Decision-making often overlooks the feedback between agents and environment. Reinforcement learning is widely employed through exploratory experimentation to address problems related states, actions, rewards, decision-making in various contexts. This work considers a new perspective, where individuals continually update their policies based on interactions with spatial environment, aiming maximize cumulative rewards learn optimal strategy. Specifically, we utilize Q-learning...
A graphene oxide (GO) membrane is an ideal separator for multiple applications due to its morphology, selectivity, controllable oxidation, and high aspect ratio of the 2D nanosheet. However, anisotropic ion conducting nature caused by morphology not favorable toward through-plane conductivity, which vital solid-state electrolytes in electrochemical devices. Here, we present a strategy selectively enhance proton conductivity GO reducing degree anisotropy with pore formation on nanosheets...
The search for new superhard materials has usually focused on strong covalent solids. It is, however, a huge challenge to design metals because of the low resistance metallic bonds against formation and movement dislocations. Here, we report microscopic mechanism enhancing hardness by identifying highly stable thermodynamic phases strengthening weak slip planes. Using well-known transition-metal borides as prototypes, demonstrate that several possess unexpectedly high whereas exhibit an...
In the design of High-temperature proton exchange membrane fuel cells (HT-PEMFC), thickness catalyst layer (CL) determines to some extent strength electrochemical performance cell and its manufacturing cost. To achieve goal improving reducing cost, genetic algorithm was employed optimize cathode anode catalytic layers. The thicknesses anode/cathode CLs were set as independent variables. results showed that best minimum adaptation value determined 0.03072. are 0.0231 mm 0.0315 mm,...
Abstract The effects of radio frequency (RF) atmospheric pressure (AP) He/H 2 plasma and thermal treatment on the hydrogenation TiO thin films were investigated compared in this work. color original film changes from white to black after being hydrogenated at 160 W (gas temperature ∼381 °C) within 5 min, while thermally treated did not change significantly even pure H or atmosphere with higher (470 longer time (30 min). This indicated that a more effective reaction happened through RF AP...
This study explores the impact of magnetic fields on operation and performance proton exchange membrane fuel cells (PEMFCs) with various flow fields. Different positions intensities were applied to investigate their effects. The PEMFCs different was then tested under field strengths arrangements. experimental results demonstrate that, same conditions, power density increases when subjected varying (180mT, 220mT, 260mT) compared no field. Furthermore, maximum higher strengths. experiments...
Every year, a large amount of tobacco waste liquid (TWL) is discharged into the environment, resulting in serious pollution for environment. In this work, TWL-based particle (OACT) was fabricated by CaO, attapulgite (ATP), and TWL, and, then, OACT coated amino silicon oil (ASO) to form OACT@ASO. Therein, OACT@ASO had high controlled-release ability fulvic acid (FA), because nanonetworks structure ATP content FA TWL. The release ratio (RR) from reached 94% at 75 h deionized water, 23% 32 d...

In the design of HT-PEMFCs, thickness catalyst layer (CL) determines to some extent strength electrochemical performance cell and its manufacturing cost. To obtain optimal CL in global range improve performance, a genetic algorithm (GA) was used optimize anode cathode thicknesses an original three-dimensional (3D) non-isothermal model. The anode/cathode CLs were set as independent variables with limited range. ratio cross-sectional area cathode/anode output power fitness function HT-PEMFC...
