A fuel cell with a gas diffusion media having a hydrophobic layer adjacent a flow field plate and a hydrophilic layer adjacent the membrane electrode assembly of the fuel cell. The two layers enable balanced humidification of reactant gas along with a basis for managing capillary water addition into the gas diffusion media. The combination of balanced moisture flux (via the hydrophobic layer) and the retention of water (via the hydrophilic layer) for humidifying reactant gas sustains hydration of the proton exchange membrane while preserving the catalyst at full activity.

Provided is a refrigerator comprising a mist atomizer disposed in a first cooling duct having a vegetable chamber discharge port and a vegetable chamber suction port. The mist atomizer is arranged inthe vicinity of a clearance between a lower-shelf storing container and an upper-shelf storing container. The refrigerator can recover the water content transpired from stored food, efficiently, and can humidify the inside of the storing container, thereby to keep the freshness at a high level.
