Abstract: The invention relates to a novel fuel cartridge for providing hydrogen gas on the basis a reactant system. Thus, a fuel cartridge for a fuel cell device, comprises a reactor compartment for storing a first reactant, a water compartment for storing water. It has a mixing compartment (106) containing a water soluble second reactant, and a fluid communication means (114) between the mixing compartment (106) and the reactor compartment (102) adapted to pass second reactant dissolved in water to the reactor compartment (102), in which the dissolved second reactant can react with the first reactant to generate a gas. Suitably, the fuel cartridge comprises an interface connectable to a water control mechanism disposed outside the cartridge, the water control mechanism configured to control a flow of the water between the water compartment and the mixing compartment such that the water mixes with and dissolves the second reactant in the mixing compartment.

Abstract: A device for mounting an electrochemical sensor unit to a skin surface of a human being comprises a mounting member having a circumferential wall, an adhesive tape at a lower end of the circumferential wall for adhering the mounting member to the skin surface, and a sealing member. The sealing member provides a liquid tight seal between a lumen or measuring chamber defined between the skin surface, the mounting device and the sensor unit, the measuring chamber being normally filled with a contact liquid. Alternatively, the sealing member is provided on the sensor unit. The provision of the sealing member renders the system less vulnerable to force impacts and reduces the risk of flawed measurements due to atmospheric air in the measuring chamber. The electrochemical sensor unit may e.g. be suitable for transcutaneous measurement of partial carbon dioxide pressure (pCO2) or partial oxygen pressure (pO2).
