double-deck crossing

Study on YSZ membrane electrolyte fuel cells supported on anode by double-layer dry pressing method;

采用一种既简单又经济的双层干压法,NiO-YSZ阳极基底上制备致密的氧化钇稳定的氧化锆(YSZ)固体电解质薄膜,经1400!共烧结后,得到厚度约60"130mm的YSZ薄膜。

It consists of a permanent magnet of SmCo28,a copper planar spring and a two-layer coil.

整个结构主要由圆形SmCo28永磁体、铜平面弹簧和双层线圈构成。
