The invention provides a tramcar based on hydrogen energy. The tramcar comprises a hydrogen fuel cell, a direct-current motor, a DC/DC voltage transformation device, a control device and a power battery, wherein the hydrogen fuel cell can output direct current, the DC/DC voltage transformation device carries out voltage transformation processing on the direct current output by the hydrogen fuel cell and provides the direct current for the direct-current motor, the power battery is electrically connected with the output end of the DC/DC voltage transformation device, and the power battery is electrically connected with the direct-current motor; when the control device receives a braking instruction, the control device obtains the counter electromotive force V1 of the direct-current motor, controls the DC/DC voltage transformation device to output direct current with the voltage of V2, and controls the power battery to be in a mode of receiving and storing electric energy. Therefore, dueto the fact that V2 is larger than V1, the current generated by the counter electromotive force cannot flow back to the hydrogen fuel cell, and the hydrogen fuel cell can be effectively prevented from being damaged.

    本发明提供一种基于氢能源的有轨电车,包括:氢燃料电池、直流电机、DC/DC变压装置、控制装置和动力电池,氢燃料电池能够输出直流电,DC/DC变压装置对氢燃料电池输出的直流电进行变压处理并提供给直流电机,动力电池与DC/DC变压装置的输出端电连接,动力电池与直流电机电连接;控制装置在接收到制动指令时,获取直流电机的反电动势V1,控制DC/DC变压装置输出电压为V2的直流电、且控制动力电池处于接收并存储电能的模式。从上所述,由于V2>V1,因此,反电动势所产生的电流是不会反灌到氢燃料电池,从而可以有效的防止氢燃料电池被损坏。
