【0019】 液体水素タンクは、、互いに対向するように配置された一対の鏡板部と、一対の鏡板部の外周縁同士を繋ぐ胴部と、を備え、内部に液体水素を貯留可能な液体水素タンクであって、鏡板部の外周縁は、曲線のみからなる第1曲線部と、曲線のみからなる第2曲線部と、第1曲線部及び第2曲線部に連結され、第1曲線部及び第2曲線部より曲率が大きい曲線のみからなる第3曲線部及び第4曲線部と、によって構成され、鏡板部の第1曲線部及び第2曲線部の少なくとも一方の領域には、内側に突出して延設される補強部が形成され、補強部の突出長さは、第3曲線部及び第4曲線部の少なくとも一方の方向に短く形成されているので、鏡板部の外周縁を曲線のみからなる第1曲線部と、曲線のみからなる第2曲線部と、第1曲線部と第2曲線部に連結され、第1曲線部及び第2曲線部より曲率が大きい曲線のみからなる第3曲線部と第4曲線部と、によって構成されることによって、車載時の設置スペースの形状に合わせて各曲線部の曲率を調整することができる。その結果、大きなデッドスペースを発生させることなく、液体水素の搭載量を増大させた液体水素タンクを設置することができる。

Abstract

This provides a liquid hydrogen tank that increases the liquid hydrogen storage capacity while improving durability. [Solution] A liquid hydrogen tank 10 is equipped with a pair of end plate sections 11 arranged facing each other and a body section 12 connecting the outer edges of the end plate sections 11, and is capable of storing liquid hydrogen inside. The outer edges of the end plate sections 11 are composed of a first curved section 13 consisting only of curves, a second curved section 14 consisting only of curves, and a third curved section 15 and a fourth curved section 16 connected to the first curved section 13 and the second curved section 14 and consisting only of curves with a greater curvature than the first curved section 13 and the second curved section 14. A reinforcing section 50 that protrudes inward is formed in at least one region of the first curved section 13 and the second curved section 14 of the end plate section 11, and the protruding length of the reinforcing section 50 is formed to be shorter in at least one direction of the third curved section 15 and the fourth curved section 16.
