Abstract

本稿では,固体高分子膜型燃料電池に空気を供給する場合と,酸素を供給する場合の発電性能の違いに着目し,この特性を利用して,燃料電池の設備容量を低減する方法を検討する。即ち,電力需要が少なく負荷が小さいときには,燃料電池で発電した電力の一部を水電解槽に供給し,生成した水素および酸素をボンベに圧縮貯蔵する。一方,電力負荷が大きいときには両ガスを放出して燃料電池で発電することで,電池容量の低減を行う。この方法を戸建住宅や病院などで構成されるエネルギーネットワークに導入したところ,従来方式と比べてトータルで36%の容量低減になるものと見積もられる。

Electric power generation performances differ by whether air is supplied to a solid high polymer film type fuel cell, or oxygen is supplied. The reduction method of the equipment capacity of the fuel cell system of having used this characteristic is considered. When electricity demand is small, a part of electric power generated by the fuel cell is supplied to a water electrolysis device, the hydrogen and oxygen which were generated by the water electrolysis are compressed, and these store in each cylinder. On the other hand, when electricity demand is large, both gases are supplied to the fuel cell system and generated. To load change of electricity demand, in this paper, as described above, the fuel cell system in consideration of reduction of fuel cell capacity is operated. If this method is introduced into the local energy network constituted from individual houses, a hospital, office, etc., it will be estimated as what becomes 36% of capacity reduction to the conventional system.
