  • Fuel cell, and collector plate thereof
    Patent number: 6808839
    Abstract: A fuel cell and a collector plate thereof that are able to improve the characteristic of distribution of reaction gasses to gas passages. Each collector plate of the fuel cell has reaction gas-conveying gas passages that are formed in stacking surfaces that face adjacent electrolyte films. Each gas passage is provided with a supply hole for distributing and supplying a reaction gas and a discharge hole for discharging the reaction gas from the gas passage. In a state where collector plates are stacked with electrolyte films placed therebetween, the supply holes connect to form a supply manifold, and the discharge holes connect to form a discharge manifold. The opening area of each discharge hole is set greater than the opening area of each supply hole.
