IPC: H01M4/96
Filed: 1988-12-08
Abstract: PURPOSE:To make the diffusion of reaction gas in an electrode substrate easy, to eliminate concentration polarization even in a high current density region, and to obtain high output voltage by specifying the thickness of the electrode substrate, and height and width of a rib. CONSTITUTION:When the thickness of an electrode substrate 1 with rib 6 comprising porous carbon is T(mm), the height of the rib 6 is D(mm) and the width of the rib 6 is C(mm), the electrode substrate 1 is formed so as to satisfy formula I. The amount of gas diffusion per area inside the electrode substrate exponentially decreases with increase in diffusion distance. In order to ensure the amount of gas diffusion corresponding to high current density, upper limit exists in diffusion distance. For example, when a fuel cell is operated at a current density of 500mA/cm<2>, diffusion distance capable of supplying a necessary amount of gas is 1.0mm or less. By increasing the amount of reaction gas diffusion, concentration polarization is eliminated even in high current density and high output voltage can be obtained.

Title: Apparatus for measuring percentage of idling time for digital signal processor and real digital signal processing system
Inventor: MASHIYUU JIEI JIEI BEA
IPC: G06F11/34
Filed: 1988-12-08
Abstract: PURPOSE: To facilitate the extension of the function of a system by allowing the 'idle loop' of a processor to involve a diagnostic instruction. CONSTITUTION: An active signal level exists in an interruption request input so that the processor 12 stops the execution of an 'idle' routine to 'trap' to an interruption handler routine stored in the different part of a program storage device 12a. The interruption handler routine realizes a desired processing by itself or shifts program control to an additional routine realizing the desired processing. Then, when the processing is completed, the processor 12 returns to the execution of the idle routine. Consequently, while the processor 12 executes a 'jumping' instruction, the state of output P1 is kept constant. Thereby a signal existing in the processor output P1 is not provided with the duty cycle of 50% to consecutively execute some steps of an idle endless loop even when the processor 12 is in the idle state by 100%.
