Fuel cell using non-linear positive temperature coefficient material

Abstract:

A fuel cell (200) includes a membrane electrode assembly (210) located together with a layer of porous, z-axis electrically conductive, non-linear positive temperature coefficient (NPTC) material (250). The NPTC material (250) operates to selectively limit the amount of electrons collected from localized areas of the membrane electrode assembly (210) in order to reduce hot spots.

Abstract(Chinese):

燃料电池（200）包括与多孔z轴导电非线性正温度系数（NPTC）材料层（250）一起定位的膜电极组件（210）。 NPTC材料（250）用于选择性地限制从膜电极组件（210）的局部区域收集的电子的量，以便减少热点。
