摘要： The present disclosure stabilizes power generation of a fuel cell stack (FCS) in an environment in which an oxygen concentration in a fuel cell system (1) readily decreases. In a case where it is detected that the oxygen concentration is lower than a predetermined concentration or where a phenomenon caused by the oxygen concentration being lower than the predetermined concentration is detected, processing to increase a flow rate of air supplied to the fuel cell stack (FCS) or processing to ventilate the interior of the fuel cell stack (FCS) by controlling an operation of a ventilation unit (F) is performed.

摘要： [Problem] Providing a fuel cell ship capable of preventing leaking fuel gas from entering and staying in a cooling medium tank, when a fuel gas leak occurs in a fuel cell.
[Solution] A fuel cell ship includes a cooling system that cools a fuel cell. The cooling system includes a cooling medium tank that accommodates a cooling medium, a cooling medium circulation pipe that circulates the cooling medium between the fuel cell and the cooling medium tank, a cooling tank internal gas detector installed in the cooling medium tank, a cooling tank internal gas discharge pipe connected to the cooling medium tank, and a cooling tank internal gas discharge valve installed in the cooling tank internal gas discharge pipe. The fuel cell ship includes a control unit that controls opening and closing of the cooling tank internal gas discharge valve. The control unit opens the cooling tank internal gas discharge valve when the cooling tank internal gas detector detects that the concentration of the fuel gas in the cooling medium tank is equal to or greater than a specified value determined in advance.

摘要： A dual purpose sensor comprising at least two electrodes and a solid polymer membrane electrolyte can serve as both a hydrogen sensor and a relative humidity sensor in the anode loop of a fuel cell system. Sensor electronics are used to apply first and second electrical signals across a pair of electrodes in the sensor, and at least one electrical parameter associated with each of the electrical signals are measured.

摘要： A hydrogen production device (350) includes: a reformer (100) which produces hydrogen-containing gas from a hydrocarbon-based raw material by a reforming reaction; a CO remover (150) which includes an oxidation catalyst, and reduces a carbon monoxide concentration in the hydrogen-containing gas with use of the oxidation catalyst by an oxidation reaction to decompose ammonia contained in the hydrogen-containing gas; a raw material supplier (20); a water supplier (30); an oxidizing gas supplier (40); a heater (10); and a controller (300). The controller (300) determines, based on a parameter related to an ammonia concentration in the hydrogen-containing gas supplied to the CO remover (150), an upper limit value of a water vapor partial pressure in the hydrogen-containing gas supplied to the CO remover (150), and changes a set value of the water vapor partial pressure to a value lower than the upper limit value.

摘要： Erfindungsgemäß wird zur Untersuchung einer Brennstoffzelle (5) mittels einer zyklovoltammetrischen Messung eine Gaszusammensetzung, insbesondere ein Wasserstoffüberschuss, in der Brennstoffzelle (5) ermittelt.
Die Erfindung lässt sich besonders vorteilhaft zur Überwachung eines Wasserstoffüberschusses in den Gasräumen (6, 7) einer lagernden oder nicht-betriebenen Brennstoffzelle (5) nutzen, insbesondere auch aus der Ferne. Sie kann aber auch sehr vorteilhaft zur Überwachung und/oder Steuerung eines Abschaltvorganges einer Brennstoffzelle (5) genutzt werden, insbesondere um dabei eine gewünschte Gasatmosphäre in der Brennstoffzelle (5) einzustellen, wie z.B. einen Wasserstoffüberschuss. Dies ist ohne Eingriffe in die Brennstoffzelle (5) mit nur einem einzigen Messgerät möglich. Es ist lediglich ein Zugang zu elektrischen Lastanschlüssen der Brennstoffzelle notwendig.
