“…As for miniaturizing a DMFC, one actual solution is a hybrid configuration consisting of a DMFC and a rechargeable battery (which has superior power density), and reports on hybrid DMFC configurations with LIBs as the rechargeable battery have been published [4]. In response, the authors have developed a hybrid system called a 'pulse-charge-control system', consisting of an electric double-layer capacitor (EDLC) [5], which has even higher power density than a rechargeable battery [6][7][8]. Although hybrid systems composed of a capacitor and a fuel cell using hydrogen as a fuel have been reported [9], no examples of reports on a hybrid system with a DMFC and a capacitor have been published.…”

A new maximum-power-point limiting (MPPL) control method for a direct methanol fuel cell (DMFC) was proposed. In regard to achieving MPPL, it was affirmed by experiment that it is possible to control the DMFC by simply ensuring that its voltage does not fall below a certain level regardless of its state. An MPPL control system that accomplishes the DMFC voltage limitation required for MPPL control by using a 'soft-start function' fitted in a ready-made DC/DC converter was developed. It was confirmed by experimental tests that the circuit board of the developed MPPL control system can perform DMFC voltage limitation control. 
