    • A sensor control apparatus includes an applied voltage control circuit connected to the positive terminal of a sensor element. The applied voltage control circuit includes a reference power supply and a noninverting amplifier circuit connected to the reference power supply. An AC power supply circuit, a buffer and a current measurement resistance are connected in series to the negative terminal of the sensor element with the current measurement resistance disposed between the AC power supply circuit and the sensor element. One terminal of the current measurement resistance, which is on the side opposite to the sensor element, is held at a reference voltage (center voltage of an AC voltage generated from the AC power supply circuit). Voltage at an intermediate point between the current measurement resistance and the sensor element is inputted via a low-pass filter to the noninverting amplifier circuit of the applied voltage control circuit.
    • 传感器控制装置包括连接到传感器元件的正极端子的施加的电压控制电路。 所施加的电压控制电路包括参考电源和连接到参考电源的同相放大器电路。 交流电源电路,缓冲器和电流测量电阻与传感器元件的负极端子串联连接,电流测量电阻设置在交流电源电路和传感器元件之间。 在与传感器元件相反的一侧的电流测量电阻的一个端子被保持在参考电压(由AC电源电路产生的AC电压的中心电压)。 通过低通滤波器将电流测量电阻与传感器元件之间的中间点处的电压输入到所施加的电压控制电路的同相放大器电路。

    • A fuel cell including separators opposing each other and squeezing a power generating reaction portion. Each of the separators includes a gas passage, a gas passage dividing rib, and a protrusion formed in the gas passage. In a first separator, which is an at least one separator of the separators opposing each other via the power generating reaction portion, at a region of the first separator opposing a gas passage dividing rib of a second separator, which is a separator opposing the first separator, a squeezing rib is formed and replaces the protrusion. The squeezing rib and the gas passage dividing rib of the second separator squeezes the power generating reaction portion. At the region of the first separator, a contact area of the squeezing rib with the power generating reaction portion is adapted to be larger than a contact area of the protrusion of the first separator with the power generating reaction portion in a case where the protrusion were formed without forming the squeezing rib.
    • 一种燃料电池,包括彼此相对的并且挤压发电反应部分的隔板。 每个分离器包括气体通道,气体通道分隔肋和形成在气体通道中的突起。 在通过发电反应部分彼此相对的分离器的至少一个分离器的第一分离器中,在第一分离器的与第二分离器的气体通道分隔肋相对的区域处,第二分离器是与第一分离器相对的分隔件 分离器,形成挤压肋并代替突起。 第二分离器的挤压肋和气体通道分隔肋挤压发电反应部。 在第一分离器的区域,挤压肋与发电反应部分的接触面积适于大于第一分离器的突起与发电反应部分的接触面积, 形成而不形成挤压肋。
