Typically, Sn cannot be finished on Ni and Ag surfaces via the immersion process. In this work, through galvanic reaction, finish was processed an coexisting with a surface. Herein, detailed mechanism of reduction Sn2+ ions surface reaction is reported. Through transmission electron microscopy X-ray diffraction analysis, uncommon Ag4Sn phase, instead common Ag3Sn confirmed to form during layer....

The study of the catalytic activity in a fuel cell is challenging, as mass transport, gas crossover and counter electrode are generally interfering. In this study, Pt consisting thin film deposited on diffusion layer was employed to oxygen reduction reaction (ORR) an operating Anion Exchange Membrane Fuel Cell (AEMFC). 2D assembled together with conventional porous Pt/C extra membrane reduce H2...
