First, the mass of the hydrolysis material cannot be accurately controlled in the feeding process, which leads to unstable hydrogen production rate in the reactor, and as the reaction proceeds, the characteristics of the reaction medium will also change, which further leads to the continuous deterioration of the hydrogen production state. Secondly, the dynamic feeding equipment generally includes a material storage bin, a material transmission bin, a water storage bin and a dynamic sealing device, which leads to a large system volume, the system is difficult to change according to the actual target demand, and there is a problem of low volume utilization rate, which reduces the energy storage density of the hydrolysis hydrogen production technology; at the same time, feeding needs to be combined with a stepping motor and various valves, which leads to a substantial reduction in volume hydrogen storage density and system power density, and is not suitable for systems with high integration and high hydrogen storage density requirements.
