Web1 jan. 2024 · These were assigned to lithium borates (Li 2 B 4 O 7) , and indicated a strong oxidation of the borohydride phase during nanoconfinement. The discrepancy between the ionic conductivity of the current LiBH 4 @MCM-41 and reported data may thus be attributed to the extensive oxidation of the complex borohydride within the scaffold material. DBFCs could be produced more cheaply than a traditional fuel cell because they do not need expensive platinum catalysts. In addition, they have a higher power density. The high operating voltage of a DBFC reduces the number of cells (in a series circuit) needed in a stack to achieve a desired rated voltage and thus reduces the stack costs considerably. chippy near altrincham football groundWeb1 jul. 2003 · A fuel cell was developed using borohydride solutions as the fuel.
