Gas conditioning device and method
A humidification device is disclosed. An illustrative embodiment of the humidification device includes at least one wet gas channel and at least one dry gas channel disposed in adjacent relationship to the at least one wet gas channel. The at least one wet gas channel and the at least one dry gas channel are adapted for exchange of moisture there between. A fuel cell system and a method of moisturizing a gas are also disclosed.
1. A fuel cell system, comprising:
a fuel cell stack;
an anode inlet, an anode outlet, a cathode inlet and a cathode outlet communicating with said fuel cell stack;
a gas conditioning device having a spiral configuration with at least one spiral dry gas channel disposed in a peripheral direction of said spirally configured gas conditioning device and communicating with said cathode inlet and at least one spiral wet gas channel similarly disposed in said peripheral direction adjacent to said at least one dry gas channel and communicating with said cathode outlet; and
wherein said at least one wet gas channel and said at least one dry gas channel are adapted for exchange of moisture there between.
2. The fuel cell system of claim 1 further comprising at least one wet gas outlet communicating with said at least one wet gas channel and an exhaust conduit communicating with said at least one wet gas outlet.
3. The fuel cell system of claim 1 further comprising at least one dry gas inlet communicating with said at least one dry gas channel and a fuel inlet communicating with said at least on a dry gas inlet.
4. The fuel cell system of claim 1 further comprising a manifold mandrel having a wet gas inlet passage communicating with said at least one wet gas channel and a moisturized gas outlet passage communicating with said at least one dry gas channel.
