1. An electrochemical gas sensor comprising:
- a gas-permeable and substantially ion-permeable and liquid-impermeable membrane for separating an aqueous outer solution and an inner electrolyte solution, and a gas-permeable film of a hydrophilic polymer consisting essentially of non-covalently cross-linked polymer chains, wherein the film is present directly at least on the side of the membrane facing the aqueous outer solution, said film having a surface wettability for the aqueous outer solution that is higher than the surface wettability of the membrane for the aqueous outer solution.

Abstract
An electrochemical gas sensor is provided comprising a gas-permeable and substantially ion- and liquid-impermeable membrane for separating an aqueous outer solution and an inner electrolyte solution comprising a gas-permeable film of a hydrophilic polymer consisting essentially of non-covalently cross-linked polymer chains, wherein the film is present directly at least on the side of the membrane facing the aqueous outer solution, which has a surface wettability for the aqueous outer solution that is higher than the surface wettability of the membrane for the aqueous outer solution.
