    • A concentration detector is disclosed, which is adapted to sense the concentration of a liquid fuel and includes an internal compartment for containing the liquid fuel. The concentration detector comprises a heater, one or more temperature sensors and a concentration calculator. The heater is disposed in the internal compartment of the concentration detector to warm up the liquid fuel. The temperature sensors are disposed in the internal compartment of the concentration detector to measure the temperature of the liquid fuel. The concentration calculator is used to receive the temperature of the liquid fuel measured by the temperature sensors, to calculate a rate of change in the temperature of the liquid fuel, and then to compute a corresponding concentration of the liquid fuel based on the rate of change in the temperature of the liquid fuel.
    • 公开了一种浓度检测器,其适于检测液体燃料的浓度,并且包括用于容纳液体燃料的内部隔室。 浓度检测器包括加热器,一个或多个温度传感器和浓度计算器。 加热器设置在浓度检测器的内部隔室中以预热液体燃料。 温度传感器设置在浓度检测器的内部室中以测量液体燃料的温度。 浓度计算器用于接收由温度传感器测量的液体燃料的温度,以计算液体燃料的温度变化率,然后基于变化率计算相应的液体燃料浓度 在液体燃料的温度下。

    • A flow field board arrangement for a fuel cell is disclosed. Injection flow channels and exhaust flow channels are individually disposed on the surface of a substrate. At least a concave portion is disposed on the same, and connected to the injection flow channel and the exhaust flow channel accordingly. An inlet is disposed on the side of the substrate and connected to an end of the injection flow channel. An outlet is disposed on the side of the substrate and connected to an end of the exhaust flow channel. The flow field board arrangement is characterized in that each injection flow channel has an identical length from an influx end of the concave portion to the inlet and/or has an equivalent flow rate, and each exhaust flow channel has an identical length from an efflux end of the concave portion to the outlet and/or has an equivalent flow rate. Additionally, the length of each injection flow channel is identical to that of each exhaust flow channel, and/or the flow rate of each injection flow channel is equivalent to that of each exhaust flow channel.
    • 公开了一种用于燃料电池的流场板装置。 注入流道和排气流通道分别设置在基板的表面上。 至少一个凹部设置在其上,并且相应地连接到喷射流动通道和排气流动通道。 入口设置在衬底的侧面上并且连接到注射流动通道的端部。 出口设置在基板侧并连接到排气流道的一端。 流场板装置的特征在于,每个喷射流动通道具有从凹入部分的入口端到入口的相同长度和/或具有等效的流速,并且每个排气流动通道具有与流出端相同的长度 的凹部和/或具有等效的流量。 此外,每个喷射流动通道的长度与每个排气流动通道的长度相同,和/或每个喷射流动通道的流量等于每个排气流动通道的流量。
