The invention discloses a hydrogen fuel cell power supply system and a hydrogen fuel vehicle thereof, relates to the field of hydrogen fuel cells, and aims to solve the problems that a hydrogen fuel cell of an existing hydrogen fuel vehicle generally can continuously generate power, but cannot be charged or recover feedback energy of regenerative braking, and a single hydrogen fuel cell configuration and a system cannot realize energy recovery and great waste is caused. According to the following technical scheme, the hydrogen fuel cell power supply system comprises a fuel cell and a whole vehicle controller which are mounted on a vehicle body; the output end of the fuel cell is connected with a DC/DC converter, the output end of the DC/DC converter is connected with a power storage battery pack and an inverter, and the output end of the inverter is connected with a motor used for driving the vehicle body to run. The fuel cell of the hydrogen fuel vehicle not only can charge and supply energy through the power storage battery pack, but also can recover feedback energy generated during braking of the vehicle body, so that energy recovery is realized, and energy waste is avoided.
本发明公开了一种氢燃料电池供电系统及其氢燃料车辆,涉及氢燃料电池领域,针对现有的氢燃料汽车的氢燃料电池一般可以持续发电,但不能充电和回收再生制动的反馈能量,单一氢燃料电池构型,系统无法实现能量的回收,造成较大浪费问题。现提出如下方案,其包括安装于车体上的燃料电池和整车控制器,所述燃料电池的输出端连接有DC/DC变换器,所述DC/DC变换器的输出端分别连接有动力蓄电池组和逆变器,所述逆变器的输出端连接有用于驱动车体行驶的电机。氢燃料汽车的燃料电池不仅能通过动力蓄电池组进行充电供能,还可以回收车体制动时产生的反馈能量,实现了能量的回收,避免了能量的浪费。
