Abstract: An electrochemical cell includes a working electrode and a counter electrode. A voltage is applied between the working electrode and the counter electrode such that electrons are supplied from the counter electrode to the working electrode so as to capture a target species. An electrode film of at least one of the working electrode and the counter electrode has an active material, a conductive aid and a binder. At least a part of the active material is contained as an agglomerate in the electrode film, and the maximum diameter of the aggregate is less than or equal to 10 μm.

Abstract: A gas recovery system configured to recover a recovery target gas from a gas mixture includes electrochemical cells and a gas passage between the electrochemical cells. The electrochemical cell has a working electrode including an adsorbent, and a counter electrode configured to exchange electrons with the working electrode. Electron donation occurs from the counter electrode to the working electrode when a voltage is applied between the working electrode and the counter electrode, such that the adsorbent adsorbs the recovery target gas along with the electron donation. At least one of the working electrode or the counter electrode includes an electrode film. The electrode film includes regions, each of which having a size smaller than a size of the electrochemical cell, and a reducing part that reduces warpage of the electrode film is located adjacent to the regions.

Abstract: An ignition control apparatus applied to an internal combustion engine including a spark plug includes an in-cylinder pressure acquisition section, a frequency signal transmitting section which transmits a frequency signal having a predetermined frequency to a switching element, and a weak discharge generating section which causes the frequency signal to be transmitted during an intake stroke and controls the frequency signal such that a weak discharge is generated at the spark plug a plurality of times. The weak discharge generating section controls the frequency signal so as to cause a duty ratio of the switching element to be changed in accordance with the in-cylinder pressure, such that the frequency of generating weak discharges during a time period in which the frequency signal is transmitted becomes higher than a predetermined frequency.

Abstract: An ignition device includes a spark plug, a measurement value detector, an electrical breakdown determiner, an AC voltage applying section, and a first changing section. The measurement value detector includes primary and secondary coils, and detects at least one measurement value among an ignition coil, a primary current, a primary voltage, a secondary current, and a secondary voltage. The electrical breakdown determiner determines whether a discharge has become an electrical breakdown state based on the measurement value. The AC voltage applying section applies an AC voltage of a first predetermined frequency that causes voltage resonance to the primary coil. The first changing section changes the frequency of the AC voltage to a second predetermined frequency that can maintain the electrical breakdown state and is lower in frequency than the first predetermined frequency when it is determined that the discharge has become the electrical breakdown state.
