提出了一种以四氢硼酸钠为燃料的制氢系统。为了控制系统向燃料电池堆（FC）供氢的量，通过控制系统中向氢反应器溶解的NaBH4的量，将FC堆的氢压力调节在燃料电池堆的保证压力范围内。然而，当FC的输出功率变化很快时，很难控制氢对堆的压力。为了稳定地调节燃料电池堆内的氢气压力，提出了一种基于实验推导的模拟模型的氢气压力控制方案。实验结果表明，即使燃料电池堆的输出功率发生变化，该方案也能稳定氢压力的振幅。
The authors have proposed a hydrogen generation system fueled by sodium tetrahydroborate. In order to control the amount of supplying hydrogen generated by the system to a fuel cell (FC) stack, the hydrogen pressure to the FC stack is regulated within warranty pressure of the stack by controlling the amount of dissolved NaBH4 to the hydrogen reactor in the system. However, it is difficult to control the hydrogen pressure to the stack when the output power of the FC changes rapidly. In this paper, a new hydrogen pressure control scheme based on experimentally-derived simulation model is proposed in order to regulate the hydrogen pressure to a fuel cell stack stably. In addition, it is shown that the proposed scheme can stabilize the amplitude of the hydrogen pressure even when the output power of fuel cell stack is changed.
