Direct borohydride fuel cell

A direct borohydride fuel cell (DBFC) is a type of fuel cell that operates in an alkaline environment and uses borohydride ions (BH4−) as the fuel source. It is one of the main types of fuel cells, alongside proton exchange membrane fuel cells, direct ethanol, formic acid, or methanol fuel cells, alkaline fuel cells, molten carbonate fuel cells, phosphoric acid fuel cells, solid oxide fuel cells, and proton ceramic fuel cells. The DBFC is unique in that it can only operate in an alkaline environment due to the instability of the BH4− ion in neutral and acidic media.From: Energy generation by membraneless microfluidic fuel cell using acidic wastewater as a fuel [2021], Electrochemically Enabled Sustainability [2019]

According to the choice of electrolyte and fuel, fuel cells are classified into six major categories as follows (Table 7.1): Proton exchange membrane fuel cell (PEMFC) Direct formic acid fuel cell (DFAFC)Direct ethanol fuel cell (DEFC)Alkaline fuel cell (AFC) Proton ceramic fuel cell (PCFC)Direct borohydride fuel cell (DBFC)Phosphoric acid fuel cell (PAFC)Molten carbonate fuel cell (MCFC)Solid oxide fuel cell (SOFC)Direct methanol fuel cell (DMFC)

The most important factors used to classify fuel cells are the electrolytes employed in the cells and the choice of fuel. The main types of fuel cells are proton exchange membrane fuel cell (PEM); direct ethanol, formic acid, or methanol fuel cell (DEFC, DFAFC, DMFC); direct borohydride fuel cell (DBFC); alkaline fuel cell (AFC); molten carbonate fuel cell (MCFC); phosphoric acid fuel cell (PAFC); solid oxide fuel cell (SOFC); and proton ceramic fuel cell (PCFC) (Chen and Chen 2006; Kirubakaran, Jain, and Nema 2009).
