燃料電池とスーパーキャパシタによるハイブリッド電源のエネルギーマネジメント
Energy Management for Fuel Cell-Supercapacitor Hybrid Power Sources System

DC-DC converter for mobile device

燃料電池は電気化学反応を利用しているという原理上,急激に発電量を変化させることが原理上難しいデバイスです。 しかし,電子機器や自動車では消費電力が頻繁に変化するため,燃料電池だけで電力供給するのに無理があります。 そこで,スーパーキャパシタという瞬発力があり充放電が半永久的に可能な新しいタイプの二次電池を燃料電池とハイブリッド化することを提案しています。 燃料電池とスーパーキャパシタをハイブリッド化するためには,燃料電池を得意な電力で動作させ, かつスーパーキャパシタの充電量を適切な範囲に保つ必要があります。 これらを可能にする電力変換回路と制御アルゴリズムの開発を進めています。(自動車用を電気電子情報工学科・星研究室と共同研究,携帯機器用を経営工学科・堂脇研究室,機械工学科・早瀬研究室と共同研究

Fuel cells, which use electrochemical reaction, can not follow steep load changing. However, electronic devices and vehicles changes their power demand and the load to fuel cells is enormous. Our idea is to combine fuel cells with supercapacitors, which can charge and discharge semipermanently at large current. To realize this idea, the fuel cells need to operate appropriate voltage and current and keep the supercapacitor’s charge within the rated value. We are developing the power electronics circuit and the algorithm. (This project is in collaboration with Hoshi Lab, Dept. Electrical Engineering for vehicle use and Dowaki Lab, Dept.
