A1-H series PEMFC stack redesigned the flow field on the basis of A1 through technical iteration, which further reduced the humidity sensitivity and made local control of the gas reaction in the active region, and further improved the uniformity.110-section 40kW separate PEMFC stack consistency is 20% higher than A1, performance is 15mV higher, single chip voltage reaches 0.65V at 600A current; It is suitable for passenger cars, heavy trucks, ships and other power scenarios. At present, it is in mass production and plans to send samples to systems and vehicle customers for trial.
