Optimisation of Mass Transport Parameters in a Polymer Electrolyte Membrane Electrolyser Using Factorial Design-of-Experiment

Optimised mass transport is crucial for high current density operations in Polymer Electrolyte Membrane Water Electrolysers (PEMWEs). This study investigates the effect and interactions of parameters on performance a PEMWE using 2 3 full-factorial Design-of-Experiments (DoE) approach with replication. The effects anode flow-field design, porous layer (PTL) water flow rate cell were studied. At 95% confidence level, result shows that all three factors their two-way significantly affect performance. Among them, showed most significant contribution, followed by interaction between PTL. A regression model was developed to relate transfer parameters. Results analysis variance (ANOVA), R test indicated good accuracy model. best obtained parallel configuration, small average pore diameter PTL rate. DoE shown be suitable method investigating optimising operating conditions maximise
