                    OPINION AND CONSENT OF HARRIS BEACH LLP


Electric Fuel Corporation
632 Broadway (Suite 301)
New York, New York 10012

Ladies and Gentlemen:

     Reference is made to our opinion dated April 30, 2001 and included as
Exhibit 5.1 to Amendment No.1 to Registration Statement on Form S-3 (File No.
333-59346) (the "Registration Statement") filed on May 1, 2001 by Electric Fuel
Corporation (the "Company") with the Securities and Exchange Commission under
the Securities Act of 1933, as amended (the "Securities Act"). We are rendering
this supplemental opinion in connection with the prospectus supplement to the
Registration Statement dated May 3, 2001 (the "Prospectus Supplement") to be
filed by the Company pursuant to Rule 424 promulgated under the Securities Act.
The Prospectus Supplement relates to the offering by the Company of 4,045,454
shares of common stock, par value $.01 per share of the Company (the "Common
Stock") and warrants to purchase an aggregate of 2,696,971 shares of Common
Stock ("the Warrants").

     We have (i) examined and relied upon original, certified, conformed,
photostat or other copies of the Amended and Restated Certificate of
Incorporation, as amended ("Amended and Restated Certificate of Incorporation")
of the Company, the Bylaws, as amended ("Bylaws") of the Company and such
other documents and records, and (ii) made such investigation of fact and such
examination of law, as we have deemed appropriate in order to enable us to
render the opinion set forth herein.  In conducting such investigation, we have
relied, without independent verification, upon the representations and/or
certificates of the officers of the Company.

     Based upon the foregoing and assuming that the Warrants are duly
executed and delivered by the Company, we are of the opinion that (i) the Common
Stock being offered pursuant to the Prospectus Supplement (including the shares
of Common Stock issuable upon the exercise of the Warrants being offered
pursuant to the Prospectus Supplement), when issued and delivered as
contemplated by the Prospectus Supplement, will be validly issued, fully paid,
and non-assessable, and (ii) the Warrants, which are governed by the laws of the
State of New York, when issued and delivered as contemplated by the Prospectus
Supplement, will be duly and validly authorized and issued and will be valid and
binding obligations of the Company.
