Claim 17:
18. An electrochemical device comprising:
a polymer electrolyte membrane, said polymer electrolyte membrane having opposing first and second faces;
an anode coupled to the first face of said polymer electrolyte membrane;
a cathode coupled to the second face of said polymer electrolyte membrane;
a gas diffusion medium in contact with the anode or the cathode to allow a flow of gas therethrough; and
a water management device having an undulating shape and extending through the gas diffusion medium to directly contact the anode or the cathode for use in delivering water thereto, said water management device being permeable to liquids and substantially impermeable to gases, said water management device comprising a first portion and a second portion, the first portion of said water management device extending through the gas diffusion medium to be in direct contact with said anode or said cathode, and the second portion of said water management device being spaced apart from said anode or cathode.
