Graphite-Based Indirect Laser Sintered Fuel Cell Bipolar Plates Containing Carbon Fiber Additions
Abstract
Critical considerations for laser sintered (LS) graphite bipolar plates are the strength of the parts in the green, brown and finished states as well as the final part electrical conductivity. The effect of 0-26 volume percent chopped carbon fiber (CF) on strength and electrical conductivity of LS graphite bipolar plates was evaluated. Fiber additions improved the green and brown strength significantly. Finished part flexural strength increased from 35 MPa to almost 50 MPa with CF additions. The electrical conductivity of finished parts was lowered by CF additions.
