    • There is provided an output circuit for supplying an output current to a load coupled to an output terminal in response to an input signal. The output circuit includes an output transistor for supplying the output current to the output terminal, an output-drive circuit for driving the output transistor, a constant-current limiting circuit for generating a current control signal for limiting the output current to a predetermined current value, and a control circuit for implementing a control such that the output current is controlled on the basis of the current control signal if a voltage at the output terminal is at a predetermined voltage, or less after the input signal is supplied while the output transistor is driven by the output-drive circuit if the voltage at the output terminal is in excess of the predetermined voltage.

    • The invention provides a method for inspecting a fuel cell that can simply inspect fuel cell characteristics.The method is an inspecting method for a direct methanol fuel cell generator comprising an anode electrode including an node catalyst layer, a cathode electrode including a cathode catalyst layer, and N pieces of cells having an electrolyte disposed between the anode electrode and the cathode electrode, for power generation by feeding an aqueous methanol solution to the anode electrode and an oxidant gas to the cathode electrode. The fuel cell generator is inspected by measuring voltage changes of the voltage V of one electromotive unit caused by generating a current density change ΔI or −ΔI (mA/cm2) satisfying the condition of 0.2≦ΔI≦5 in a finite current density I (mA/cm2) loaded on the plural electromotive units arbitrarily connected in series in the fuel cell generator under power generation during a time interval Δt (sec) satisfying the condition of 10−5≦Δt≦0.5.
