Advantage:1)High power density: The volume power density in the end plate reaches 4.2kW/L, which is comparable to the metal plate stack2)Independent research and development of core components: independent research and development of key components3)Ultra-thin graphite composite plate, using ultra-thin graphite composite plate technology, the thickness is only 1/2-1/3 of the thickness of traditional graphite plate4)Creative technical solution: The self-developed VLS II stack achieves a low hydrogen cycle ratio of <50% and a low humidification requirement of 40% @70C;the proprietary material and structural design enable it to meet the requirements of long service life and multiple cycles.
