【発明の名称】燃料電池用加湿装置、燃料電池膜を加湿するための方法、および燃料電池
Document Type and Number:
Japanese Patent JP2003535434
Kind Code:
A
Abstract:
The humidifying device for a fuel cell has a membrane, one side of which is exposed to cathode exhaust gas of a fuel cell for extracting water vapor from the exhaust gas. A connecting element connects the other side of the membrane to an anode or cathode gas supply to the fuel cell. In operation, water vapor permeates through the membrane and passes on through the connecting elements to humidify the gas being supplied to the fuel cell. A vacuum pump may additionally be provided to enhance the extraction of water vapor from the exhaust gas. A no metering unit allows accurate metering of the humidity of the cathode or anode gas supply.
