A water transport assembly, is provided including a housing having a first chamber therein, which is accessible through an opening in the housing. The housing additionally includes a sample inlet port and a sample outlet port, both of which are in fluid communication with the first chamber. A flat ion exchange membrane is attached to the housing in a plane over the opening in the housing, to seal the opening in a vapor tight seal. Water will pass through the membrane based upon the vapor pressure on each side of the membrane, to either dry or humidify sample passing through the first chamber. When the flat ion exchange membrane is a flat, thin ion exchange membrane it is preferable that the thin ion exchange membrane have a thickness of between about 0.1 and about 3.0 mils.

The self-watering assembly is used in combination with a conventional planter having flow hole apertures formed within a base thereof. The assembly includes a set of water-permeable flow hole inserts each including a portion of capillary material such as spandex. The flow hole inserts are inserted into a flow hole of the planter for direct contact with soil positioned therein. The flow hole inserts are sized and shaped to securely fit within the flow hole preventing soil from falling out of the flow hole and preventing roots from growing through the flow hole. Additional capillary material, also formed of spandex, couples an interior of a water reservoir to the capillary material of the water-permeable inserts. By using spandex as the capillary material, sufficient capillary flow may be achieved to properly water even medium to large sized plants. By employing water-permeable inserts for insertion into the planter wherein the inserts have capillary material mounted therein, water can be more effectively drawn into the soil of the planter as compared to many self watering planters wherein the planter merely rests on capillary material. Also, upon removal of the planter from the water reservoir, the inserts typically remain mounted within the flow holes of the planter such that soil from the planter is prevented from falling out of the planter via the flow holes. Entirely conventional planters may be employed thereby reducing overall costs which permit the customer a wide choice of planter shapes and sizes.

The present invention is a fuel cell power plant that includes a fuel cell having a membrane electrode assembly (MEA), which is disposed between an anode support plate and a cathode support plate, and porous water transport plates adjacent the anode and cathode support plates. The porous water transport plates have interdigitated flow channels for the reactant gas streams to pass therethrough and conventional flow channels for a coolant stream to pass therethrough. The fuel cell power plant also has means for creating a pressure differential between the reactant gas streams and the coolant stream such that the pressure of the reactant gas streams is greater than the coolant stream. Incorporating the interdigitated flow channels into the porous water transport plates and operating the fuel cell at a pressure differential allows the coolant water to saturate the water transport plates thereby forcing the reactant gases into the anode and cathode support plate. This, in turn, increases the mass transfer of such gases into the support plates, thereby increasing the electrical performance of the fuel cell. Current densities of about 1.6 amps per square meter are achieved with air stochiometries of not over 2.50.
