Abstract
A bipolar plate for a battery includes a metal sheet that has a first side and a second, opposite side. The metal sheet is folded so as to form a series of loops on the second side. The loops are spaced apart to define flow field passages therebetween on the second side. Each of the loops is bonded along an edge at the first side so as to enclose an internal passage.
Claims20
A bipolar plate for a battery, comprising:
- a metal sheet having a first side and a second side opposite the first side, the metal sheet being folded so as to form a series of loops on the second side, the loops being spaced apart to define flow field passages therebetween on the second side, each of the loops being bonded along an edge at the first side so as to enclose an internal passage.
A battery comprising:
- at least one cell including
- a metal anode;
- a cathode;
- and
- an electrolyte between the metal anode and the cathode,
- the cathode including a bipolar plate having a metal sheet defining a negative first side and a positive second side opposite the negative first side, the metal sheet being folded so as to form a series of loops on the positive second side, the loops being spaced apart to define flow field passages therebetween on the positive second side, each of the loops being bonded along an edge at the negative first side so as to enclose an internal passage.

A method for fabricating a bipolar plate for a battery, comprising:
- providing a substantially flat metal sheet that has a first side and a second side opposite the first side;
- bending the metal sheet to form a series of loops on the second side, the loops being spaced apart to define flow field passages therebetween on the second side;
- and
- bonding each of the loops along an edge at the first side so as to enclose an internal passage.
