| 摘要 |
A water detection device comprising at least one fuel cell comprising a first electrode, a layer of electrolyte, a second electrode and an electrical measurement device characterized in that the first electrode of the cell is in contact with a first face of a porous silicon substrate comprising Si—H bonds, in such a manner as to liberate a flow of hydrogen in the presence of water. Advantageously, the substrate of porous silicon is incorporated into a first housing permeable to water, the fuel cell being incorporated into a second housing said second housing being impermeable to water and permeable to oxygen. |
