Channel two-phase flow validation and dynamics in proton exchange membrane fuel cells under water-boiling-point temperature conditions

With the growing demand for green energy, proton exchange membrane fuel cells (PEMFCs) have developed worldwide. Increasing the operating temperature to the water-boiling-point range (100–120 ℃) can significantly enhance the heat dissipation capacity, but it induces more complex...

Prussian blue regulates ion dynamics in perovskite solar cells

Perovskite photovoltaics are limited by structural instabilities initiated during crystallization and amplified under operation. We report that a lattice-matched Prussian blue scaffold directs heterogeneous nucleation to produce highly oriented, strain-relaxed films. Its redox-ac...

Design and optimization of the external manifold with a spider-web-inspired perforated sheet for solid oxide fuel cells

The gas flow distribution in solid oxide fuel cell (SOFC) stacks has a significant impact on the electro-thermal-mass transport performance and safety. In this study, an external manifold structure incorporating a spider-web-inspired perforated sheet is designed for a planar SOFC...
