摘要： A condenser (10), for cooling a gas flow containing a vapor to promote condensation of the vapor, has a generally cylindrical chamber. Gas is admitted at one end of the chamber and is given a swirl component of velocity. The gas then travels axially along the length of the chamber, and passes radially through holes (55, 57) into the bore of a separator. The swirl velocity of the gas flow tends to through water droplets radially outwards, where they can drain down the inside of a casing defining the chamber. The separator can include a skirt portion (52) separating the main chamber (40) from a water collection compartment. Cooling to cause condensation is provided by an external jacket (110), preferably having a coolant flowing through it in a helical fashion.

摘要： Fuel cell modules usually have an inherently limited load slew rate, which is adequate for some applications but insufficient where close load following is desired. An example of where the inherent lack of dynamic response, of a typical fuel cell module, has proven to be insufficient is within a standalone AC power generation system in which the fuel cell module does not, or cannot, possibly, receive a priori knowledge of current demand changes by load. In contrast, the present invention aims to provide a current controller for use in a fuel cell system, a fuel cell system with adaptive current control and a method of operating a fuel cell system that employs an adaptive current controller that enables a relatively fast dynamic response to abrupt increases in current demand whilst also providing a controlled adjustment to the output current provided by a fuel cell module included in the system. The adaptive current control system includes a fuel cell module, an ultra-capacitor, a current limiter, and a processor with several inputs and at least one output for detecting and controlling current conditions in the fuel cell system.

摘要： The electrical energy produced by a fuel cell under test is typically dumped in the form of heat energy radiated from a controllable variable load included in a conventional fuel cell testing system. This practice is wasteful since the electrical energy produced is not immediately employed to do useful work, stored for later use or sold to a power company after appropriate conversion. According to aspects of some embodiments of the present invention there is provided a fuel cell testing system having an energy conversion system that converts electrical energy produced by a fuel cell under test into another reliable form of energy that can be employed for some useful end, as opposed to simply dumping it as radiated heat energy.

摘要： This invention discloses a system and method for monitoring the voltage of a fuel cell stack. The system comprises a plurality of differential amplifiers, a switching network, an analog to digital converter and a controller. The system may further include a remote PC. Each differential amplifier has a high common-mode rejection ratio. The differential amplifiers are connected to terminals in the fuel cell stack at which the voltage is to be measured. An output of a single differential amplifier is chosen by the switching network, under the direction of the controller, and converted to digital values by the analog to digital converter. The digital values are used by the controller to calculate the cell voltage of the fuel cell. The controller also controls the analog to digital converter. The invention further comprises a calibration method and apparatus which are used to calibrate the measurement system before performing voltage measurement on the fuel cell stack. This invention allows the cells voltage of a fuel cell with almost any common-mode voltage to be measured using readily available differential amplifiers.

摘要： A method and apparatus are provided for measuring impedance and voltage characteristics of cells of multi-cell electrochemical devices, for example a battery or a fuel cell stack. Voltages are measured across individual cells, or groups of cells. At the same time, a load is connected in series with the electrochemical device. Both the device for measuring the voltages and the load are controlled together, preferably by means of a controller, which can include some form of microprocessor. This enables the load to be controlled to provide a desired combination of DC and AC current characteristics. By setting appropriate DC and AC current characteristics, desired characteristics of the impedance of individual cells can be measured.
