FUEL CELL INLET AIR PROCESSOR

摘要

Fuel cell stacks (27, 28) each receive air from an inlet air processor (20) having water porous and hydrophilic water wafers having semi-circumferential channels (62) leading from a water inlet (72) to a water outlet (73) intimately contacting back sides of porous and hydrophilic air wafers (52) having radial channels (56, 57). Water from the water wafers is transfused into the air wafers and evaporated into the air, cooling and humidifying the incoming air, the labyrinth-like flow of air through the air flow channels (56, 57) reducing the blower inlet and exit noise, and washing minute particulate contaminants from the air. Air and water channels may be on separate wafers or on opposite surfaces of the same wafer.
