摘要： The measuring range of a fuel cell based concentration sensor can be extended by decreasing the load across the fuel cell terminals and by increasing the amount of oxidant supplied to the fuel cell. In this way, such a sensor avoids saturation, for example, when measuring methanol concentrations from 0 M to over 4 M in liquid aqueous solution. Such a sensor is suitable for use in measuring fuel concentrations in the recirculating fuel stream of certain fuel cell stacks (for example, direct methanol fuel cell stacks).
摘要翻译：基于燃料电池的浓度传感器的测量范围可以通过减少燃料电池端子两端的负载和增加供给到燃料电池的氧化剂的量来延长。以这种方式，这种传感器避免饱和，例如在液体水溶液中测量从0M至超过4M的甲醇浓度时。这种传感器适用于测量某些燃料电池堆（例如直接甲醇燃料电池堆）的再循环燃料流中的燃料浓度。

摘要： A sensor outputs a signal related to a concentration of methanol in an aqueous solution adjacent the sensor. A membrane electrode assembly (MEA) is included with an anode side and a cathode side. An anode current collector supports the anode side of the MEA and has a flow channel therethrough for flowing a stream of the aqueous solution and forms a physical barrier to control access of the methanol to the anode side of the MEA. A cathode current collector supports the cathode side of the MEA and is configured for air access to the cathode side of the MEA. A current sensor is connected to measure the current in a short circuit across the sensor electrodes to provide an output signal functionally related to the concentration of methanol in the aqueous solution.

摘要： An apparatus for determining the endpoint in a chemical mechanical polishing operation used for polishing a metal-containing material includes an electrochemical cell and an electronic circuit. An acidic polishing slurry is used to oxidize the metal and the oxidized metal is included in an effluent slurry stream, a sample of which is provided to the apparatus. The apparatus includes a liquid-phase working electrode, a reference electrode and a solid electrolyte which allows for the interchange of ions between the electrodes. An electronic circuit is coupled to the electrode for monitoring the component activity of the effluent slurry stream by measuring the electric potential across the electrodes. When the measured electric potential changes, indicating a change in the composition of the effluent slurry, endpoint is indicated.
