Our research focuses on IoT-integrated hydrogen fuel cells for clean energy in Inner Mongolia and Hebei, China. The system features a 100 kW PEMFC array (65–80 ℃, 98% pure H₂, 850 mbar) paired with an optimized AWS IoT Cloud using MQTT/LoRaWAN for 1 Hz data communication. AI-driven EMS optimizes operations (35–85% load, 30–80% battery charge), while predictive maintenance via Random ...

Riverbank filtration is used for producing a large amount of groundwater for a long time. The surface water infiltration is accompanied with riverbank filtration and may significantly affect the quality and temperature of pumping water if the pumping well is located nearby the river. A coupled groundwater flow and heat transport model was developed to estimate the influence of surface water on ...
