In this paper, the N = 2 fermionic extensions of the KdV equations are derived from the zero curvature condition associated with the graded Lie algebra of OSp(2/2). These equations lead to two bi-Hamiltonian systems, one of which is supersymmetric. The authors also derive the one-parameter family of N = 2 supersymmetric KdV equations without a bi-Hamiltonian structure in this approach. Following the authors' earlier proposal, the authors interpret the zero curvature conditions as a gauge anomaly equation which brings out the underlying current algebra for the corresponding 2D supergravity theory. This current algebra is then used to obtain the operator product expansions of various fields of this theory.
