Sounds promising:
"More than twice the power:
To achieve a high power density, the researchers from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) designed a 70 kW-level stack, which is more than twice as powerful as the current 30 kW-level stack. They used self-developed materials, such as weldable porous composite membranes and weldable highly conductive bipolar plates, to create a stack with a short flow path, an ultra-thin battery structure, low flow resistance, and high distribution uniformity flow channels.
The result is a stack with a volume power density of 130 kW/m3, and a cost reduction of 40%. The stack also has a high energy efficiency of over 80% under different power conditions, and a stable performance after more than 1,200 cycles, with only 1.7% energy efficiency decay."
