1. this new fuel cell device uses a kind of two-sided runner plate with waveform configuration, can allow fuel cell (particularly fuel cell pack) whole volume and weight all significantly reduce, and this helps fuel cell integrated to portable consumption electronic products.

2. this new fuel cell device utilizes the rigidity of two-sided runner plate plate body itself, thereby collector plate can be fabricated to structure as thin as a wafer, can allow the volume of fuel cell itself and weight significantly reduce.

3. the employed two-sided runner plate of this new fuel cell device can have the plate body of the idioelectric engineering plastics material of chemical resistance by use, the collector plate of electric conducting material is set again, so not only can allow the in light weight of fuel cell and have portable convenience, and make two-sided runner plate have good current collection function simultaneously.

4. the employed two-sided runner plate of this new fuel cell device can prevent effectively that fuel (as: methyl alcohol) or electrochemical reaction product from destroying the surface of collector plate, thereby reduces the rate of changing of eliminating of fuel cell.

Be familiar with this technology personage and understand this novel purpose, feature and effect for making, now by following specific embodiment, and conjunction with figs., to this novel explanation in detail as after.
