    • The data communication apparatus of the present invention includes a CPU, operation panel, reading unit, image memory for storing read image data, resolution converter for converting stored image data to an optional resolution, telephone communication unit for transmitting data over a telephone line, network communication unit for transmitting data over an internet line, and a printing unit. The resolution converter converts fine detail data to low detail data and sends the low detail data to the telephone communication unit when transmitting data over the telephone line. In this way data reception reliably occurs simultaneously with data transmission. Thereafter, when fine detail request data including resolution data are received over the telephone line, the data are converted to the desired resolution, and sent to the network communication unit. In this way the apparatus attains excellent operationality since fine detail data are transmitted only as necessary.

    • 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.
