Heat Transfer Optimization of NEXA Ballard Low-Temperature PEMFC

Hydrogen is one of the modern energy carriers, but its storage and practical use newest hydrogen technologies in real operation conditions still a task future investigations. This work describes experimental hybrid system (HHS). HHS part laboratory off-grid that stores electricity gained from photovoltaic panels (PVs). includes production units NEXA Ballard low-temperature proton-exchange membrane fuel cell (PEMFC). Fuel (FC) loses significant heat during converting chemical into electricity. The main purpose study was to explore distribution phenomena across FC stack load with next transfer optimization. insufficient cooling can lead overheating or even destruction. cause this undesirable state studied help infrared thermography computational fluid dynamics (CFD) modeling simulation stack. under various loads studied, local points were determined. Based on obtained data air streamlines velocity profiles, few ways optimization along proposed. achieved by changing original shape duct. stable condition at constant
