Embodiment 1
[0027] The metal anode 1 of the metal oxygen battery adopts AZ31 magnesium alloy anode with an area of 9.6cm 2 , the oxygen cathode cavity 8 is passed into air (oxygen therein is an oxidizing agent), H 2 -O 2 The fuel cell porous metal anode 4 adopts 110PPI porous nickel foam coated with Pd on the surface, with an area of 4.8cm 2 , Mg-O 2 battery cathode 5 and H 2 -O 2 The fuel cell cathode 6 is coated with MnO 2 The cathode of the catalyst, the diaphragm material 7 is a glass fiber woven mesh. The inlet electrolyte 2 is 3.5% NaCl solution at a temperature of 20°C, and the insulating material 9 is AB glue. From the battery inlet, the electrode presses Mg-O 2 Cathode 5 and H 2 -O 2 The cathode 6 is arranged once. Mg-O 2 battery cathode 5 and H 2 -O 2 The fuel cell cathode area is equal (both are 4.8cm 2 ). Mg-O 2 When the battery is not discharged, due to the small amount of hydrogen evolution, the H 2 -O 2 The open circuit voltage of the fuel cell is only...
Embodiment 2
[0029] Mg-O 2 The area of cathode 5 is larger than H 2 -O 2 Fuel cell cathode 6 area, from cell inlet, electrode by Mg-O 2 Cathode 5 and H 2 -O 2 Fuel cell cathodes 6 are alternately arranged, (respectively 6.5cm 2 , 3cm 2 , 6.5cm 2 , 3cm 2 ), the metal anode area of the metal oxygen battery is 19cm 2 , H 2 -O 2 Fuel cell porous metal anode area is 6cm 2 . Other conditions are with embodiment 1. In Mg-O 2 Battery 23mA / cm 2 During constant current discharge, H 2 -O 2 Battery performance such as Figure 4 shown.
[0030] Mg-O 2 Current density 23mA / cm 2 When discharging with constant current, its output power is 300mW. After 5 minutes of discharge in a magnesium-oxygen battery, the H 2 -O 2 When the fuel cell anode potential gradually rises to 1.15V, start testing H 2 -O 2 Fuel cell discharge current-voltage curve ( Figure 4 ). h 2 -O 2 Battery current density 23mA / cm 2 When discharging, the maximum power density reaches 12.6mW / cm 2 , the reco...
Embodiment 3
[0033] The metal anode 1 of the metal oxygen battery adopts the anode with a purity of 99.96% Al, and the electrolyte uses 4N NaOH and 0.05M Na 2 SnO 3 Solution, other conditions are with embodiment 2.
[0034] Al-O 2 When the battery is not discharged, because Al has a certain corrosion in 4N NaOH solution, H 2 -O 2 The open circuit voltage of the fuel cell can reach 0.86V. Al-O 2 Battery current density 23mA / cm 2 When discharging with constant current, its output power is 321mW. in Al-O 2 After the battery is discharged for 5 minutes, the H 2 -O 2 When the open circuit voltage of the fuel cell gradually rises to 1.21V, start testing H 2 -O 2 Fuel cell discharge current-voltage curve ( Figure 5 ). h 2 -O 2 Fuel cell current density 25mA / cm 2 When discharging, the power density reaches 19.3mW / cm 2 , the recoverable energy is 115.8mW, accounting for Al-O 2 36.1% of battery power generation. Al-O 2 Battery at 23mA / cm 2 During electric dense discharge, the h...
