Controlling cellulose fiber viscosity to 150-500 ml/g suppresses capacitance and voltage drops under high temperature while reducing heat generation.
A separator incorporating beaten solvent-spun cellulose fibers and rayon fibers with controlled diameter ratios to enhance entanglement and surface strength.
Electrospun nanofibers reinforce the fuel cell membrane-electrode assembly, resolving brittleness while increasing power density by 27%.
Segmented crimping avoids terminal corners, preventing electrode foil damage and improving vibration resistance.
