摘要： A fuel cell system and an operation method thereof are capable of re-starting the system reliably even after the system has been tilted to or beyond a predetermined limit. The fuel cell system includes a fuel cell having an anode and a cathode. A tilt sensor detects a tilt of the fuel cell system not smaller than a predetermined limit, and a memory stores a record that the fuel cell system was tilted to or beyond the predetermined limit. When the fuel cell is started thereafter, the fuel cell is started in a recovery mode if there is a record of a tilt not smaller than the predetermined limit in the memory. The fuel cell is not started, however, if a tilt time since the detection of the tilt of the fuel cell system not smaller than the predetermined limit is not smaller than a first predetermined value.

摘要： The level of electrical current produced by a fuel cell during rapid changes in the power demanded by a load, is clamped to the fuel cell's maximum rated current value in order to avoid damage to the fuel cell. When the current supplied to the load by the fuel cell overshoots the maximum rated current value, the fuel cell current is immediately reduced by increasing the fuel cell voltage.

摘要： A switching system and control method therefor are provided and implemented with a fuel cell stack system. The switching system enables fuel cell stacks to be connected in series for providing power to a power user while removing the particular disadvantages of a series circuit. In the event of a stack fault, the faulty stack may be bypassed, whereby the remaining stacks provide power to the power user at reduced capacity. The stack is continuously monitored and is reintroduced to the series circuit if the fault clears. If the fault reoccurs a predetermined number of times after the stack has been reintroduced, a “reduced capacity” mode is initiated. Additionally, in the event of a reduced or an increased current demand, stacks are selectively switched in and out of the series connection, for limiting the overall operation voltage range of the fuel cell stack system.

摘要： Species detection techniques are described based on measurement of a dynamic response to an external stimulus. One embodiment includes a voltage stimulus applied to a polymer electrolyte fuel cell (PEFC), with the response to said stimulus used to measure CO concentration on the anode catalyst. The principles of symbolic dynamics, finite state machines or a simplified peak response-to-asymptotic value measurement can be used to achieve a high degree of precision for measuring CO concentrations. Using the techniques of the present invention, CO poisoning of a fuel cell can be monitored and diagnosed before reaching a critical condition, thereby allowing early implementation of mitigation or graceful degradation strategies.

摘要： A fuel cell system determines each of a battery charging current error, a battery voltage error, and a stack current error. The fuel cell system regulates current through a series pass element in response to a greater of the determined errors. Thus, the fuel cell system operates in three modes: battery voltage limiting mode, stack current limiting mode and battery charging current limiting mode. Additionally, there can be a fourth “saturation” mode where the stack voltage VS drops below the battery voltage VB as the load pulls even more current. Individual fuel cell systems can be combined in series and/or parallel to produce a combined fuel cell system having a desired output voltage and current.

摘要： In a power supply device including a fuel cell unit with a stack of fuel cells or a fuel cell stack and a secondary battery, an intermittent drive mode is selected under a preset condition to receive power supply only from the secondary battery. The control procedure of the invention determines whether a temporary stop of the fuel cell stack or continuance of the stop of the fuel cell stack leads to potential performance deterioration of the fuel cell stack at a restart of the fuel cell unit. In response to estimation of the potential performance deterioration, the control procedure controls the power supply device to continue or start power generation of the fuel cell stack, regardless of selection of the intermittent drive mode under the preset condition.
