Abstract

Two-dimensional model and simulation programs for designing a hydrogen storage vessel using hydrogen absorbing alloy with tubular heat exchanger were developed with the “Flow-3D” program in which physical properties of the hydrogen storage alloy were incorporated. The calculated results showed good agreement with experimental data obtained from 10 Nm3 scale hydrogen storage vessel with MmNi4.64Al0.36 alloy. It was concluded that this simulation program could be an adequate tool to design a practical scale hydrogen storage system for hydrogen from solid polymer electrolyte water electrolysis and to evaluate its hydrogen storage performance.

관형 열교환기를 갖는 수소흡수합금을 이용한 수소저장용기 설계를 위한 2차원 모델 및 시뮬레이션 프로그램은 수소저장합금의 물성을 반영한 “Flow-3D” 프로그램으로 개발하였다. 계산된 결과는 MmNi 4.64 Al 0.36 합금 이 있는 10 Nm 3 규모의 수소 저장 용기 에서 얻은 실험 데이터와 잘 일치하는 것으로 나타났습니다. 이 시뮬레이션 프로그램은 고체 고분자 전해질 물 전기분해에서 수소를 위한 실용적인 규모의 수소 저장 시스템을 설계하고 수소 저장 성능을 평가하는 데 적절한 도구가 될 수 있다는 결론을 내렸습니다.
