Abstract
A fuel cell component that includes a porous fuel cell plate and a solid frame contiguously extending all around the fuel cell plate is made by first forming an integral plate-shaped porous body including a central portion constituting the fuel cell plate and a peripheral portion integral with and circumferentially completely surrounding the central portion, and then impregnating the pores of only the peripheral portion with a quantity of initially flowable but solidifiable impregnating material such that the impregnating material is accommodated in and completely fills such pores and makes the peripheral portion solid and completely fluid-impermeable upon solidification of the impregnating material to constitute the frame.
