摘要:
An membrane electrode assembly for a fuel cell composed of a pair of electrode catalyst layers and an electrolyte membrane sandwiched between the electrode catalyst layers is configured so that the catalyst of at least one surface of the electrode catalyst layers enters in the electrolyte membrane whereby the electrode catalyst layer and the electrolyte membrane are unified with each other. In this configuration, no exfoliation occurs at the interface between the electrode catalyst layer and the electrolyte membrane, and the durability of the membrane electrode assembly can be increased even during the course of heat cycles.
摘要:
A microcomputer MCU adopting the general purpose register method is enabled to have a small program capacity or a high program memory using efficiency and a low system cost, while enjoying the advantage of simplification of the instruction decoding as in the RISC machine having a fixed length instruction format of the prior art, by adopting a fixed length instruction format having a power of 2 but a smaller bit number than that of the maximum data word length fed for instruction execution. And, the control of the coded division is executed by noting the code bits.
摘要:
A division method and circuit performs a division for signed data by adding or subtracting a divisor to or from the dividend or the partial remainder from the division, according to the sign of the divisor or the dividend and the partial remainder to acquire a new partial remainder. The division is repeated a predetermined number of times in which a quotient bit is acquired according to the sign of the acquired partial remainder or the divisor. The dividend is corrected by subtracting 1, which is the significance of an LSB of the corresponding dividend, from the dividend when the sign of the dividend is negative, and the corrected dividend is used for the division processing.
