一种可以提高燃料电池运行稳定性的导流极板
摘要：
本发明涉及一种可以提高燃料电池运行稳定性的导流极板，包括空气导流极板或氢气导流极板或由空气导流极板与氢气导流极板相背组合一体的导流双极板；所述的空气导流极板设有一对或多对进、出空气的流体孔，该一对或多对流体孔之间设有多条呈平行直条状弯曲空气导流槽；所述的氢气导流极板设有一对或多对进、出氢气的流体孔，该一对或多对流体孔之间设有多条呈平行直条状弯曲导氢气流槽，所述的空气导流极板上还设有一对或多对冷却流体孔，在该一对或多对流体孔之间并在空气导流槽的背面设有冷却流体导流槽。与现有技术相比，本发明具有结构简单、加工方便，安装实施后有利于提高燃料电池运行稳定性等特点。
摘要（英）：

The invention can be composed of air diversion plate or hydrogen diversion plate or diversion bipolar plate comprising of air diversion plate and hydrogen diversion plate. The air diversion plate has one or multi pair of fluid holes for air entering and exhausting. Multi air diversion trenches are set between the fluid holes. The hydrogen diversion plate has one or multi pair of fluid holes for hydrogen entering and exhausting. Multi hydrogen diversion trenches are set between fluid holes. The air diversion plate also has one or multi pair of cooling fluid holes. The cooling fluid diversion trench is set between cooling fluid holes and at the back of air diversion trench.
