The construction of a microcellular carbon foam/epoxy resin composite electrode is described. The large perimeter-to-area ratio (P/A) of the resulting microelectrode array is desirable and represents an improvement in P/A over that of many composites presently in use. The array is characterized by using chronoamperometry and cyclic voltammetry. The results are compared to those of both a glassy carbon electrode and microelectrode array theory. The responses obtained are representative of expected behavior. The capacity of the electrode was 2.1 {times} 10{sup 3} {mu}F/cm{sup 2}, 2 orders of magnitude greater than that expected for carbon.
