水が滞ることなく循環するものは無かった。2. Description of the Related Art Conventionally, a fuel gas and an oxidant gas of a fuel cell have been supplied orthogonally to each other by a manifold structure. There is also an example (Japanese Patent Application No. 3-154558) in which an internal header system is used and a separator allowing parallel flow of fuel gas and oxidant gas is used, but as can be seen from the example, the gas flow direction is gravity. There was no cooling water circulating in the lower direction.

方もしくは両方を加湿する方法がとられている。By the way, when a solid polymer membrane is used as an electrolyte, it often cannot exhibit high performance as an electrolyte unless it is sufficiently hydrated.
For example, Nafion (made by DuPont), which is a proton conductor, is typical. When a fuel cell is constructed using these solid polymer membranes, a method for supplying water to the membranes is to humidify one or both of gases introduced as a fuel and as an oxidant.

ことがある。セパレータの表面にはガス供給用の細い溝
があるが、この細い溝がドレンで被われてしまうとガス
供給が不可能となり、性能が著しく低下してしまう。However, depending on the operating conditions of the fuel cell, water may drain on the surface of the separator. There is a thin groove for gas supply on the surface of the separator, but if the thin groove is covered with drain, gas supply becomes impossible and the performance remarkably deteriorates.

The flow had to remove the drain.
